Using 3.1M2.

Is this repeatable? If so, can you provide us with a testcase?
I hate to say this, but: Repeatable: Don't know Test case: No This was in a big project. Some of the classes needed for building were provided by .jar files. I had sources for those classes, and I had informed Eclipse about those sources. Then I decided I needed to change some of those sources, and added the source path to the project's source paths. During the following re-build, this happened. I don't think I'm able to re-trace my steps. I do realize however that this might be hard for you to track down without a repro case, so if you can't do anything about this with the provided information you'll have to close this as INVALID or WORKSFORME.
Please reopen if you can reproduce. There have been several changes affecting cycle detection released since 3.1M2, so your case may already be fixed.
Closing as never reproduced in a long time
I've hit this bug numerous times recently refactoring a large project in M4 - M5a. The last time I hit it I was using the Move Member Type to New File refactoring on a static class within a generic class. The nested class did not reference the type variable of the outer class. Here's the stack trace: java.lang.NullPointerException at org.eclipse.jdt.internal.compiler.lookup.TypeVariableBinding.boundCheck(TypeVariableBinding.java:73) at org.eclipse.jdt.internal.compiler.lookup.ParameterizedTypeBinding.resolve(ParameterizedTypeBinding.java:632) at org.eclipse.jdt.internal.compiler.lookup.BinaryTypeBinding.resolveType(BinaryTypeBinding.java:53) at org.eclipse.jdt.internal.compiler.lookup.BinaryTypeBinding.superclass(BinaryTypeBinding.java:774) at org.eclipse.jdt.internal.compiler.lookup.ClassScope.detectHierarchyCycle(ClassScope.java:957) at org.eclipse.jdt.internal.compiler.lookup.ClassScope.detectHierarchyCycle(ClassScope.java:919) at org.eclipse.jdt.internal.compiler.ast.ParameterizedSingleTypeReference.internalResolveType(ParameterizedSingleTypeReference.java:143) at org.eclipse.jdt.internal.compiler.ast.ParameterizedSingleTypeReference.resolveType(ParameterizedSingleTypeReference.java:208) at org.eclipse.jdt.internal.compiler.ast.TypeReference.resolveSuperType(TypeReference.java:104) at org.eclipse.jdt.internal.compiler.lookup.ClassScope.findSupertype(ClassScope.java:1051) at org.eclipse.jdt.internal.compiler.lookup.ClassScope.connectSuperclass(ClassScope.java:710) at org.eclipse.jdt.internal.compiler.lookup.ClassScope.connectTypeHierarchy(ClassScope.java:846) at org.eclipse.jdt.internal.compiler.lookup.CompilationUnitScope.connectTypeHierarchy(CompilationUnitScope.java:243) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.completeTypeBindings(LookupEnvironment.java:195) at org.eclipse.jdt.internal.compiler.Compiler.beginToCompile(Compiler.java:307) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:321) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile(AbstractImageBuilder.java:225) at org.eclipse.jdt.internal.core.builder.AbstractImageBuilder.compile(AbstractImageBuilder.java:175) 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:581) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:1015) at org.eclipse.core.runtime.Platform.run(Platform.java:757) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:160) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:198) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:227) at org.eclipse.core.internal.runtime.InternalPlatform.run(InternalPlatform.java:1015) at org.eclipse.core.runtime.Platform.run(Platform.java:757) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:230) at org.eclipse.core.internal.events.BuildManager.basicBuildLoop(BuildManager.java:249) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:278) at org.eclipse.core.internal.events.AutoBuildJob.doBuild(AutoBuildJob.java:138) at org.eclipse.core.internal.events.AutoBuildJob.run(AutoBuildJob.java:199) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:67)
