Bug 26611 Code completion assumes multiple args of same type will take same value
|
Build 20021115 (M3) 1) Start with the following JCU: public abstract class A { private int fieldInt = 5; public void foo(int a, int b, int c) { } public void bar() { int integer = 5; fo<cursor-is-here> } } 2) Invoke code assist at the cursor position indicated above 3) From the list of completions, select the method foo -> It guesses the parameter values, and highlights and underlines the first value, "integer". So far so good. 4) Type "fieldInt" as the first parameter value. -> It replaces all three parameters with the value "fieldInt". Not expected, but fine. 5) Hit tab to accept the guess for the first parameter. -> The cursor goes to the end of the line. What I expect: The method "foo" has three distinct parameters. I would expect to have to hit tab three times, once for each parameter. This template assumes that there is only one variable to complete, and that all three parameters of type "int" will have the same value.

Bug 26699 Create Jar fails with no warning if jar read-only
|
Once *.jardesc has been created, if I invoke "Create JAR" from the context menu and the jar file already exists and is read-only, the progress dialog flashes and nothing more happens. Please add check for this condition and at least an error message should be displayed. Even better, ask something like "Jar file read-only, overwrite?" Y/N and overwrite the file on yes (similar to what the option "warn if jar file exists" does).

Bug 26498 No feedback when deleting empty package which is not a leaf [refactoring]
|
Build 20021114 1. Disable filtering of empty packages 2. Select an empty package which is not a leaf (e.g. junit.samples) 2. Delete it ==> no feedback, nothing happens. I see two solutions 1) Dialog informs the user about the fact that this thing can't be removed 2) Dialog asks the user if he want to delete everything below two This wasn't an issue so far but when deleting empty nodes in the Package Explorer with hierarchical layout it is weird to get no feedback.

Bug 26074 getter and setter wizard doesn't work for subclasses
|
With the following code block: public class Foo { protected String someString; } class Bar extends Foo { } If the Generate Getter and Setter wizard is opened inside the Bar class, a message indicating that the "operation not applicable to current text selection". Since a getter/setter has not been created in the superclass Foo, I think that Bar should be able to create the methods. If a field is added to Bar, the wizard is displayed but it still does not allow a getter/setter to be built for the someString field.

If I open the Navigator in the Java Browsing perspective and select a non-jaa project, the Packages view shows the folders in the project as empty packages. I would have expected the packages view to be empty in this case.

Bug 25370 Linked Mode: Want to define where to focus
|
20021022 I added a new feature that starts the linked mode on all usages of a variable. e.g. int i; i= 1; i++; would link all 3 occurrences of i, so when edited, all 3 references are changed simultanously. Problem is that the liked mode does not allow me to set the focus (where to edit) to e.g. the 'i' in 'i++'. The linked mode only allows to edit the top most linked position ('int i'). The feature can be invoked on any reference. Jumping to the top not so ideal.

Bug 25370 Linked Mode: Want to define where to focus
|
20021022 I added a new feature that starts the linked mode on all usages of a variable. e.g. int i; i= 1; i++; would link all 3 occurrences of i, so when edited, all 3 references are changed simultanously. Problem is that the liked mode does not allow me to set the focus (where to edit) to e.g. the 'i' in 'i++'. The linked mode only allows to edit the top most linked position ('int i'). The feature can be invoked on any reference. Jumping to the top not so ideal.

The compiler warns about an unnecessary import, while the organize imports does not remove it. This can be reproduced with these sources: MyClass.java: import MyInterface.MyInnerInterface; public class MyClass implements MyInterface{ public MyInnerInterface myMethod() { return null; } } MyInterface.java: public interface MyInterface { public interface MyInnerInterface { } }

Bug 26746 Organize Imports leaves an unnecessary import of inner interface [code manipulation]

The compiler warns about an unnecessary import, while the organize imports does not remove it. This can be reproduced with these sources: MyClass.java: import MyInterface.MyInnerInterface; public class MyClass implements MyInterface{ public MyInnerInterface myMethod() { return null; } } MyInterface.java: public interface MyInterface { public interface MyInnerInterface { } }

1) open the outline pop-up (ctrl-O) 2) type in a letter ->observe that you can watch how the tree items are removed and then added again. Use of setRedraw(false/true) during filtering should avoid this flickering

Bug 26546 In/correct quick fix for non-static access to static member [quick fix]
|
I have classes like so: com.me.Common extends org.junit.TestCase and com.me.MyTest extends Common. In my test, I have JUnit assertXXX calls coded like so: this.assertXXX(...); I therefore get warnings for non-static access to static members, which is nice! The quick fix changes this: this.assertXXX(...); to this: MyTest.assertXXX(...); I was expecting: Assert.assertXXX(...); Any thoughts? Aside from the quick fix wouldn't Assert... be "more correct"?

Bug 26546 In/correct quick fix for non-static access to static member [quick fix]
|
I have classes like so: com.me.Common extends org.junit.TestCase and com.me.MyTest extends Common. In my test, I have JUnit assertXXX calls coded like so: this.assertXXX(...); I therefore get warnings for non-static access to static members, which is nice! The quick fix changes this: this.assertXXX(...); to this: MyTest.assertXXX(...); I was expecting: Assert.assertXXX(...); Any thoughts? Aside from the quick fix wouldn't Assert... be "more correct"?

Bug 25098 Quickfix for The local variable may not have been initialized.. [quick fix]
|
Often I write code like this: String name; try { name = "Good value"; int val = name.indexOf(42); } catch(Exception e) { throw new RuntimeException("Something went wrong with " + name); } The declaration of name is placed outside the try clause to provide access to it inside the catch. Here eclipse (as it should) complains that "The local variable name may not have been initialized". How about providing a QuickFix that assigned null to the uninitialized variable (e.g. "String name = null")

Bug 25098 Quickfix for The local variable may not have been initialized.. [quick fix]
|
Often I write code like this: String name; try { name = "Good value"; int val = name.indexOf(42); } catch(Exception e) { throw new RuntimeException("Something went wrong with " + name); } The declaration of name is placed outside the try clause to provide access to it inside the catch. Here eclipse (as it should) complains that "The local variable name may not have been initialized". How about providing a QuickFix that assigned null to the uninitialized variable (e.g. "String name = null")

Bug 25098 Quickfix for The local variable may not have been initialized.. [quick fix]
|
Often I write code like this: String name; try { name = "Good value"; int val = name.indexOf(42); } catch(Exception e) { throw new RuntimeException("Something went wrong with " + name); } The declaration of name is placed outside the try clause to provide access to it inside the catch. Here eclipse (as it should) complains that "The local variable name may not have been initialized". How about providing a QuickFix that assigned null to the uninitialized variable (e.g. "String name = null")

Bug 25098 Quickfix for The local variable may not have been initialized.. [quick fix]
|
Often I write code like this: String name; try { name = "Good value"; int val = name.indexOf(42); } catch(Exception e) { throw new RuntimeException("Something went wrong with " + name); } The declaration of name is placed outside the try clause to provide access to it inside the catch. Here eclipse (as it should) complains that "The local variable name may not have been initialized". How about providing a QuickFix that assigned null to the uninitialized variable (e.g. "String name = null")

Bug 27878 infinite loop?

build N1206 on Win2K, IBM VM 1.3.1 in the big workspace I started up, opened the java perspective and navigated to org.eclipse.core.resources/src. When I clicked to expand the src folder my CPU went to 100% for alone time (forever?). Using ctrl-break I got the attached core dump which indicates that the RenameSupport.create() method appears to be called infinitely. Note that memory use does not seem to be increasing.

Bug 27687 Jar export: Cannot export java project as a jar when manifest file is present
|
Steps to reproduce: 1. Create a java project 2. Create a simple folder in your project. Call it "META-INF". 3. Create a simple file in the META-INF folder. Call it "MANIFEST.MF". 4. In the context menu of your java project, click "Export" and select JAR file. 5. Fill in the export destination path and click Next. 6. Click Next again to go to the JAR Manifest Specification page of the wizard. The same thing happens whether you choose "Generate the manifest file" or "Use existing manifest from workspace" and select the file, then click Finish. The popup appears: Confirm Replace The file 'E:\eclipse_workbench\eclipse\workspace\Test.jar' already exists. Do you want to overwrite it? Yes No No: takes you back to the JAR Manifest Specification page of the JAR Export wizard. Yes: brings up the following error popup: JAR Export JAR creation failed. See details for additional information Details: Problem writing /<project name>/META-INF/MANIFEST.MF to JAR: duplicate entry: META-INF/MANIFEST.MF

Bug 22164 Referencing JavaPlugin class in earlyStartup causes invalid thread access [misc]
|
It is possible that this is not a bug, either because it's known & not supported to because it's internal API, but it was rather unexpected, bizzare behavor. I have a plugin which depends on JDT-UI. This plugin also happens to implement IStartup. If at anypoint, I load the org.eclipse.jdt.internal.ui.JavaPlugin class from earlyStartup(), the Plugin loader attempts to load JDT-UI, which then promptly bombs out with invalid thread access and fails to load. This only happens if no JDT UI perspectives are loaded (in other words, on a fresh workspace). I will attach a simple plugin that demonstrates the problem. Just run it on a fresh workspace. The line it fails on seems to be "manager.registerAdapters(new JavaElementAdapterFactory(), IJavaElement.class);" in the startup() method. Thanks, Andrew
