Hi folks I get an internal compiler error with a rather long exception, like this: Internal compiler error java.lang.NullPointerException at org.eclipse.jdt.internal.compiler.lookup.ParameterizedTypeBinding.enclosingType(ParameterizedTypeBinding.java:256) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.createRawType(LookupEnvironment.java:497) at org.eclipse.jdt.internal.compiler.lookup.ParameterizedTypeBinding.swapUnresolved(ParameterizedTypeBinding.java:873) at org.eclipse.jdt.internal.compiler.lookup.UnresolvedReferenceBinding.setResolvedType(UnresolvedReferenceBinding.java:75) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.createBinaryTypeFrom(LookupEnvironment.java:405) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.createBinaryTypeFrom(LookupEnvironment.java:393) at org.eclipse.jdt.internal.compiler.Compiler.accept(Compiler.java:190) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.askForType(LookupEnvironment.java:99) at org.eclipse.jdt.internal.compiler.lookup.UnresolvedReferenceBinding.resolve(UnresolvedReferenceBinding.java:43) at org.eclipse.jdt.internal.compiler.lookup.BinaryTypeBinding.resolveType(BinaryTypeBinding.java:85) at org.eclipse.jdt.internal.compiler.lookup.ParameterizedTypeBinding.resolve(ParameterizedTypeBinding.java:752) at org.eclipse.jdt.internal.compiler.lookup.BinaryTypeBinding.resolveType(BinaryTypeBinding.java:65) at org.eclipse.jdt.internal.compiler.lookup.BinaryTypeBinding.resolveTypesFor(BinaryTypeBinding.java:752) at org.eclipse.jdt.internal.compiler.lookup.BinaryTypeBinding.getExactMethod(BinaryTypeBinding.java:568) at org.eclipse.jdt.internal.compiler.lookup.Scope.findExactMethod(Scope.java:789) at org.eclipse.jdt.internal.compiler.lookup.Scope.getMethod(Scope.java:2159) at org.eclipse.jdt.internal.compiler.ast.MessageSend.resolveType(MessageSend.java:314) at org.eclipse.jdt.internal.compiler.ast.MessageSend.resolveType(MessageSend.java:258) at org.eclipse.jdt.internal.compiler.ast.CastExpression.resolveType(CastExpression.java:380) at org.eclipse.jdt.internal.compiler.ast.LocalDeclaration.resolve(LocalDeclaration.java:201) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolveStatements(AbstractMethodDeclaration.java:415) at org.eclipse.jdt.internal.compiler.ast.MethodDeclaration.resolveStatements(MethodDeclaration.java:169) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolve(AbstractMethodDeclaration.java:393) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:1063) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:1112) at org.eclipse.jdt.internal.compiler.ast.CompilationUnitDeclaration.resolve(CompilationUnitDeclaration.java:305) at org.eclipse.jdt.internal.compiler.Compiler.process(Compiler.java:504) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:329) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile(AbstractImageBuilder.java:240) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile(AbstractImageBuilder.java:190) at org.eclipse.jdt.internal.core.builder.IncrementalImageBuilder.build(IncrementalImageBuilder.java:114) at org.eclipse.jdt.internal.core.builder.JavaBuilder.buildDeltas(JavaBuilder.java:227) at org.eclipse.jdt.internal.core.builder.JavaBuilder.build(JavaBuilder.java:155) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:593) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:1038) at org.eclipse.core.runtime.Platform.run(Platform.java:775) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:168) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:202) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:231) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:1038) at org.eclipse.core.runtime.Platform.run(Platform.java:775) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:234) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:253) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:282) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:139) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:200) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:67) I hope this can tell you something, because I don't feel I can say much. It is only one file this is happening on, and I have that thing already seen on 31M6 and 31M7 while I am now using RC1. I don't really know which part of the code it doesn't like, I tried to delete stuff and see what happens, but I haven't found the one piece of code. For example: I delete one method, and the error goes away. But when I put the method in an isolated class, the error doesn't show. So it seems to not be related to this method, or something in it in particular, but rather to that method in combination with the rest of the class. Oh, and the error manifests itself like this: State 1: no error Action: I change something, add a comment for example. State 2: changed Action: I save State 3: saved + error Action: I change again something, for example I add a dot and delete it State 4: changed Action: I save State 5: saved and no error State 5 wraps to State 1 again, so I have to save the file always twice now. I hope this helps Cheers Daniel
You should have a compilation unit with a marker that is refering to the NPE. Could you please provide the source code of this class and its dependants to help us to reproduce the problem? Thanks.
(In reply to comment #1) It does show a red marker, but it puts it on the first line of the file. (The first line is inhabited by a comment only.) When I then visit the "Problems" view and check the entry there, it contains the shown exception stack trace. I'll try to extract the file into a blank project without dependencies. Gimme a minute :)
The marker is on the first line because of the crash. There is no line to report the problem as this is an internal error. Thanks for attaching the test case.
Created attachment 22324 [details] A minimal project, zipped completely. The class in question is this one: IndexedSparseMatrix
I don't get the exact same NPE in latest. It crashes in org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.createRawType(...). Once this is fixed, we might ask you to verify it with your test case. Here is a simpler test case: package test; public class A { A() { new B().bar(); } } package test; import java.util.Map; import java.util.Set; import java.util.SortedSet; public class B { public Set<Map.Entry> bar() { return null; } void foo(SortedSet<Map.Entry> set) { } } When both are compiled at the same time, it works. But then change A and recompile, this leads to the following stack trace. java.lang.NullPointerException at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.convertToRawType(LookupEnvironment.java:356) at org.eclipse.jdt.internal.compiler.lookup.ParameterizedTypeBinding.enclosingType(ParameterizedTypeBinding.java:255) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.createRawType(LookupEnvironment.java:569) ... This looks like a problem with binary type binding.
I confirm that using M7, I get the exact same stack trace than the original test case using the simpler test case in comment 5.
Even simpler test case: B.java import java.util.Map; import java.util.Set; import java.util.SortedSet; public class B { static Set<Map.Entry> foo(SortedSet<Map.Entry> set) { return null; } } -------------------------------------- A.java public class A { A() { B.foo(null); } }
Added GenericTypeTest#test714
