With Cheetah04 and I200404220800, one class of my project doesn't compile anymore. It worked with 03. The stack trace is shown below. I wasn't able to create a minimal set of classes to reproduce the bug. If I modify and save another class, the affected class compiles correctly. The generated code seems to run. Once I edit the affected class, the error occurs again. Internal compiler error java.lang.Error: Undefined base type: > at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.getTypeFromSignature(LookupEnvironment.java:649) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.getTypeFromTypeSignature(LookupEnvironment.java:691) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.getTypeFromVariantTypeSignature(LookupEnvironment.java:742) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.getTypeArgumentsFromSignature(LookupEnvironment.java:564) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.getTypeFromTypeSignature(LookupEnvironment.java:697) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.getTypeFromVariantTypeSignature(LookupEnvironment.java:742) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.getTypeArgumentsFromSignature(LookupEnvironment.java:564) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.getTypeFromTypeSignature(LookupEnvironment.java:697) at org.eclipse.jdt.internal.compiler.lookup.BinaryTypeBinding.createFields(BinaryTypeBinding.java:241) at org.eclipse.jdt.internal.compiler.lookup.BinaryTypeBinding.cachePartsFrom(BinaryTypeBinding.java:223) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.createBinaryTypeFrom(LookupEnvironment.java:312) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.createBinaryTypeFrom(LookupEnvironment.java:297) at org.eclipse.jdt.internal.compiler.Compiler.accept(Compiler.java:191) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.askForType(LookupEnvironment.java:81) at org.eclipse.jdt.internal.compiler.lookup.UnresolvedReferenceBinding.resolve(UnresolvedReferenceBinding.java:43) at org.eclipse.jdt.internal.compiler.lookup.BinaryTypeBinding.resolveType(BinaryTypeBinding.java:49) at org.eclipse.jdt.internal.compiler.lookup.PackageBinding.getTypeOrPackage(PackageBinding.java:158) at org.eclipse.jdt.internal.compiler.lookup.CompilationUnitScope.findOnDemandImport(CompilationUnitScope.java:355) at org.eclipse.jdt.internal.compiler.lookup.CompilationUnitScope.findSingleTypeImport(CompilationUnitScope.java:414) at org.eclipse.jdt.internal.compiler.lookup.CompilationUnitScope.faultInImports(CompilationUnitScope.java:291) at org.eclipse.jdt.internal.compiler.lookup.CompilationUnitScope.faultInTypes(CompilationUnitScope.java:341) at org.eclipse.jdt.internal.compiler.Compiler.process(Compiler.java:518) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:333) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile(AbstractImageBuilder.java:209) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile(AbstractImageBuilder.java:159) at org.eclipse.jdt.internal.core.builder.IncrementalImageBuilder.build(IncrementalImageBuilder.java:113) at org.eclipse.jdt.internal.core.builder.JavaBuilder.buildDeltas(JavaBuilder.java:223) at org.eclipse.jdt.internal.core.builder.JavaBuilder.build(JavaBuilder.java:151) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:544) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:609) at org.eclipse.core.runtime.Platform.run(Platform.java:541) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:148) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:240) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:178) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:208) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:609) at org.eclipse.core.runtime.Platform.run(Platform.java:541) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:211) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:259) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:288) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:150) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:189) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:66) The affected class contains no ">" if that matters. Neither does its superclass. Both classes do NOT use generics or other 1.5 features. The only other class the first class refers to is a class using List<Player> in a different package. If I recreate the szenario in a new project, I can't reproduce that error :(
Could you please provide your test case? Thanks.
This is a .class file related problem. You will need to change & compile a class that refers to the type causing problems so that we read it as a .class file.
As I tried to explain - unfortunately, I've no test case. And franky, I don't want to attach my whole project here...
Created attachment 9974 [details] Test case Okay, got it. The attached test.zip contains a project where compiling "PT" raises the internal error. If you edit "Cmd", the error goes away and if you edit "PT" it comes back. Hope this helps.
Reproduced. Thanks for the good test case.
We misgenerate a type signature, and thus fail to decode it: Ljava/util/List<Lgame/Game<>;>;
Reduced test case is: import java.util.List; public class X { private List<X> games; } Signature for field is incorrect, and thus causing incremental compilation failure. Adding regression test: GenericTypeSignatureTest#test014
Fixed.
