In my particular case, if I compile this project using a JDK1.3 "javac", it will compile. However, when I am using the compiler that comes with WSAD Version 4.0.2, it is not able to compile. (NOTE: The version choices in the bug report indicate 1.0 and 2.0, I have no idea how to tell what I have) I get a message box popping up that says "Errors During Build" and details points to ===> org.eclipse.jdt.internal.compiler.lookup.SourceTypeBinding The log file says: Log: Thu Mar 07 14:19:10 EST 2002 2 org.eclipse.core.resources 2 Problems occurred when invoking code from plug- in: org.eclipse.core.resources. java.lang.ClassCastException: org.eclipse.jdt.internal.compiler.lookup.SourceTypeBinding at org.eclipse.jdt.internal.compiler.lookup.BlockScope.emulateOuterAccess (BlockScope.java:297) at org.eclipse.jdt.internal.compiler.lookup.BlockScope.propagateInnerEmulation (BlockScope.java:1144) at org.eclipse.jdt.internal.compiler.ast.AllocationExpression.analyseCode (AllocationExpression.java(Compiled Code)) at org.eclipse.jdt.internal.compiler.ast.AllocationExpression.analyseCode (AllocationExpression.java(Compiled Code)) at org.eclipse.jdt.internal.compiler.ast.SingleNameReference.analyseAssignment (SingleNameReference.java(Compiled Code)) at org.eclipse.jdt.internal.compiler.ast.Assignment.analyseCode(Assignment.java (Compiled Code)) at org.eclipse.jdt.internal.compiler.ast.Block.analyseCode(Block.java(Compiled Code)) at org.eclipse.jdt.internal.compiler.ast.IfStatement.analyseCode (IfStatement.java(Compiled Code)) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.analyseCode (AbstractMethodDeclaration.java(Compiled Code)) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.analyseCode (TypeDeclaration.java:145) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.analyseCode (AbstractMethodDeclaration.java(Compiled Code)) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.analyseCode (TypeDeclaration.java(Compiled Code)) at org.eclipse.jdt.internal.compiler.ast.CompilationUnitDeclaration.analyseCode (CompilationUnitDeclaration.java:67) at org.eclipse.jdt.internal.compiler.Compiler.process(Compiler.java:379) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java(Compiled Code)) at org.eclipse.jdt.internal.core.builder.impl.AbstractImageBuilder.compile (AbstractImageBuilder.java:90) at org.eclipse.jdt.internal.core.builder.impl.BatchImageBuilder.build (BatchImageBuilder.java(Compiled Code)) at org.eclipse.jdt.internal.core.builder.impl.JavaDevelopmentContextImpl.createStat e(JavaDevelopmentContextImpl.java:146) at org.eclipse.jdt.internal.core.builder.impl.JavaBuilder.fullBuild (JavaBuilder.java:148) at org.eclipse.jdt.internal.core.builder.impl.JavaBuilder.build (JavaBuilder.java:46) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:93) at org.eclipse.core.internal.runtime.InternalPlatform.run (InternalPlatform.java:761) at org.eclipse.core.runtime.Platform.run(Platform.java:393) at org.eclipse.core.internal.events.BuildManager.basicBuild (BuildManager.java:114) at org.eclipse.core.internal.events.BuildManager.basicBuild (BuildManager.java:73) at org.eclipse.core.internal.events.BuildManager.basicBuild (BuildManager.java:41) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:140) at org.eclipse.core.internal.runtime.InternalPlatform.run (InternalPlatform.java:761) at org.eclipse.core.runtime.Platform.run(Platform.java:393) at org.eclipse.core.internal.events.BuildManager.basicBuild (BuildManager.java:154) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:214) at org.eclipse.core.internal.resources.Project.build(Project.java:110) at org.eclipse.ui.actions.BuildAction.invokeOperation(BuildAction.java:90) at org.eclipse.ui.actions.WorkspaceAction.execute(WorkspaceAction.java:111) at org.eclipse.ui.actions.WorkspaceAction$1.execute(WorkspaceAction.java:268) at org.eclipse.ui.actions.WorkspaceModifyOperation$1.run (WorkspaceModifyOperation.java:64) at org.eclipse.core.internal.resources.Workspace.run(Workspace.java:1197) at org.eclipse.ui.actions.WorkspaceModifyOperation.run (WorkspaceModifyOperation.java:78) This is extremely reproduceable. I'm trying to create a smaller test case of the problem but I have isolated the offending "java" source code to one particular file.
It looks like a duplicate of 6378. If you can isolate a test case, we could confirm this is fixed in the 2.0 stream.
I am still working on trying to skinny down the failing source. (There's about 271 source files in this project I'm dealing with and I can't really send all this source to you). I will look at problem #6378 as well to see what it says. Thanks!
Here is an isolated test case for the problem we solved in 6378. If you have a pattern of code close to this, then this is fixed in 2.0. public class A { public Object foo() { B b = new B() { protected Object bar() { return new B.C() {}; } }; return b; } } class B { class C { } } If you compile this code in 1.0, you'll get the same stacktrace than the one you provided. Did you try to compile your code in a 2.0 build?
The failing source java file does have a pattern similar to what you describe. It's beaucoup inner classes. Is it possible to get this fix against the Eclipse 1.0 base ?
No this is unlikely, since so many changes did occur in this area in between 1.0 and 2.0. Attempting to issue a patch would be hard, and likely causing some more troubles. You may want to change your source code for the short term (until you get a refreshed WSAD build based on Eclipse 2.0). The following would compile fine in 1.0: public class X { public Object foo() { B b = new B() { protected Object bar() { return new B.C(this) { }; } }; return b; } } class B { static class C { C(B b){ } } }
I just wanted to document that I did try the Eclipse 2.0 build (20020214) and the problem is resolved.
