I received this error when invoking build all. I was trying to clear a spurious error about missing an implementation that an ITD would fix from a previous incremental compilation. A clean and rebuild fixed this... java.lang.NullPointerException at org.aspectj.org.eclipse.jdt.internal.compiler.lookup.MethodBinding.sourceMethod(MethodBinding.java:748) at org.aspectj.org.eclipse.jdt.internal.compiler.lookup.MethodBinding.sourceStart(MethodBinding.java:755) at org.aspectj.ajdt.internal.compiler.lookup.EclipseSourceType.fillDeclaredMembers(EclipseSourceType.java:211) at org.aspectj.ajdt.internal.compiler.lookup.EclipseSourceType.getDeclaredMethods(EclipseSourceType.java:263) at org.aspectj.weaver.ReferenceType.getDeclaredMethods(ReferenceType.java:512) at org.aspectj.weaver.ResolvedType.addAndRecurse(ResolvedType.java:263) at org.aspectj.weaver.ResolvedType.getMethodsWithoutIterator(ResolvedType.java:258) at org.aspectj.weaver.ResolvedType.lookupResolvedMember(ResolvedType.java:379) at org.aspectj.weaver.JoinPointSignatureIterator.findSignaturesFromSupertypes(JoinPointSignatureIterator.java:178) at org.aspectj.weaver.JoinPointSignatureIterator.hasNext(JoinPointSignatureIterator.java:69) at org.aspectj.weaver.patterns.SignaturePattern.matches(SignaturePattern.java:287) at org.aspectj.weaver.patterns.WithincodePointcut.matchInternal(WithincodePointcut.java:72) at org.aspectj.weaver.patterns.Pointcut.match(Pointcut.java:146) at org.aspectj.weaver.patterns.NotPointcut.matchInternal(NotPointcut.java:52) at org.aspectj.weaver.patterns.Pointcut.match(Pointcut.java:146) at org.aspectj.weaver.patterns.AndPointcut.matchInternal(AndPointcut.java:51) at org.aspectj.weaver.patterns.Pointcut.match(Pointcut.java:146) at org.aspectj.weaver.ShadowMunger.match(ShadowMunger.java:75) at org.aspectj.weaver.Checker.match(Checker.java:70) at org.aspectj.weaver.bcel.BcelClassWeaver.match(BcelClassWeaver.java:2806) at org.aspectj.weaver.bcel.BcelClassWeaver.matchInvokeInstruction(BcelClassWeaver.java:2768) at org.aspectj.weaver.bcel.BcelClassWeaver.match(BcelClassWeaver.java:2506) at org.aspectj.weaver.bcel.BcelClassWeaver.match(BcelClassWeaver.java:2332) at org.aspectj.weaver.bcel.BcelClassWeaver.weave(BcelClassWeaver.java:494) at org.aspectj.weaver.bcel.BcelClassWeaver.weave(BcelClassWeaver.java:119) at org.aspectj.weaver.bcel.BcelWeaver.weave(BcelWeaver.java:1606) at org.aspectj.weaver.bcel.BcelWeaver.weaveWithoutDump(BcelWeaver.java:1557) at org.aspectj.weaver.bcel.BcelWeaver.weaveAndNotify(BcelWeaver.java:1335) at org.aspectj.weaver.bcel.BcelWeaver.weave(BcelWeaver.java:1155) at org.aspectj.ajdt.internal.compiler.AjPipeliningCompilerAdapter.weaveQueuedEntries(AjPipeliningCompilerAdapter.java:455) at org.aspectj.ajdt.internal.compiler.AjPipeliningCompilerAdapter.queueForWeaving(AjPipeliningCompilerAdapter.java:392) at org.aspectj.ajdt.internal.compiler.AjPipeliningCompilerAdapter.afterProcessing(AjPipeliningCompilerAdapter.java:380) at org.aspectj.ajdt.internal.compiler.CompilerAdapter.ajc$after$org_aspectj_ajdt_internal_compiler_CompilerAdapter$5$6b855184(CompilerAdapter.aj:98) at org.aspectj.org.eclipse.jdt.internal.compiler.Compiler.process(Compiler.java:533) at org.aspectj.org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:329) at org.aspectj.ajdt.internal.core.builder.AjBuildManager.performCompilation(AjBuildManager.java:892) at org.aspectj.ajdt.internal.core.builder.AjBuildManager.doBuild(AjBuildManager.java:273) at org.aspectj.ajdt.internal.core.builder.AjBuildManager.incrementalBuild(AjBuildManager.java:172) at org.aspectj.ajde.internal.CompilerAdapter.compile(CompilerAdapter.java:117) at org.aspectj.ajde.internal.AspectJBuildManager$CompilerThread.run(AspectJBuildManager.java:191) trouble in: class glassbox.track.api.UIStatisticsType extends glassbox.track.api.UofwStatisticsType: private static transient glassbox.util.logging.api.LogManagement ajc$glassbox_util_logging_api_LogManagement$ptwAspectInstance [Synthetic] public void <init>() org.aspectj.weaver.MethodDeclarationLineNumber: 130:4443 : ALOAD_0 // Lglassbox/track/api/UIStatisticsType;

sort out for 1.5.3 - possibly a real error was hiding behind this NPE - a guard may be sufficient.
Hi Ron, I've not been able to reproduce this....are you able to provide a minimal testcase which shows the NPE? Thanks, Helen
Under a separate bug I've made a bit of a radical change to support for ITDs in incremental compilation. That change may affect this. The fix hasn't yet reached AJDT - should be soon.
Just as a note...the latest upgrade of the compiler within ajdt was taken on the 20th October.
I've just seen this same NPE whilst doing some refactoring work with aspectj build 1.5.3.200610201049. I'm still trying to reproduce this with a simplified testcase but as yet have had no luck. The aspects involved do not have ITD's, just deow statements.
I've still been unable to reproduce this with a simplified testcase, although in my development workspace it happens fairly frequently. The NPE occurs when I remove a method from an interface that causes a compiler error in another class. When I try to fix the compiler error the NPE occurs. This is similar to Ron's initial description.

multiple bugs point to this one - going to put the guard in at least.
guard is in - will be in dev build shortly.
