During compiling a class I'll get this exception: java.lang.NullPointerException at org.aspectj.org.eclipse.jdt.internal.compiler.lookup.ParameterizedTypeBinding.getMethodsBase(ParameterizedTypeBinding.java:471) at org.aspectj.org.eclipse.jdt.internal.compiler.lookup.ParameterizedTypeBinding.getMethods(ParameterizedTypeBinding.java:1041) at org.aspectj.org.eclipse.jdt.internal.compiler.lookup.Scope.findMethod(Scope.java:1060) at org.aspectj.org.eclipse.jdt.internal.compiler.lookup.Scope.getMethod(Scope.java:2165) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.MessageSend.resolveMethodBinding(MessageSend.java:480) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.MessageSend.resolveType(MessageSend.java:347) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.CastExpression.resolveType(CastExpression.java:380) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.MessageSend.resolveType(MessageSend.java:326) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.MessageSend.resolveType(MessageSend.java:326) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.LocalDeclaration.resolve(LocalDeclaration.java:199) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolveStatements(AbstractMethodDeclaration.java:422) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.MethodDeclaration.resolveStatements(MethodDeclaration.java:178) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolve(AbstractMethodDeclaration.java:400) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:1088) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:1137) at org.aspectj.org.eclipse.jdt.internal.compiler.ast.CompilationUnitDeclaration.resolve(CompilationUnitDeclaration.java:305) at org.aspectj.org.eclipse.jdt.internal.compiler.Compiler.process(Compiler.java:519) at org.aspectj.org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:329) at org.aspectj.ajdt.internal.core.builder.AjBuildManager.performCompilation(AjBuildManager.java:974) at org.aspectj.ajdt.internal.core.builder.AjBuildManager.doBuild(AjBuildManager.java:262) at org.aspectj.ajdt.internal.core.builder.AjBuildManager.doBuild(AjBuildManager.java:214) at org.aspectj.ajdt.internal.core.builder.AjBuildManager.incrementalBuild(AjBuildManager.java:185) at org.aspectj.ajde.core.internal.AjdeCoreBuildManager.doBuild(AjdeCoreBuildManager.java:88) at org.aspectj.ajde.core.AjCompiler.build(AjCompiler.java:96) at org.eclipse.ajdt.core.builder.AJBuilder.build(AJBuilder.java:198) at org.eclipse.core.internal.events.BuildManager$2.run(BuildManager.java:624) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:37) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:166) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:197) at org.eclipse.core.internal.events.BuildManager$1.run(BuildManager.java:246) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:37) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:249) at org.eclipse.core.internal.events.BuildManager.basicBuild(BuildManager.java:214) at org.eclipse.core.internal.events.BuildManager.build(BuildManager.java:353) at org.eclipse.core.internal.resources.Project.internalBuild(Project.java:494) at org.eclipse.core.internal.resources.Project.build(Project.java:75)
passing over to compiler
are you able to tell me anything about the class? Is it pure java? is it generic?
It is pure java and would compile with 1.4 (no generics, no enums, ...) I could not post the whole class here, I'm sorry. Is there a way to get more debug output from ajdt than the thread dump?
If you are able to check that it compiles under Eclipse 3.2 (or later) as pure java than I will mark this as a bug in AspectJ because we are currently based on the 3.1 compiler and so it will be fixed when we upgrade. There are no extra diagnostics I could ask you to turn on - the only further thing you could do is try and distill the essence of your type into a simple example class that you could append on here that shows the problem.
It is pure java and compile without AspectJ with JRE 5 Execution Environment in Eclipse 3.3. This is our current environment. One thing to mention is that the class has parent classes from Apache Cocoon. But that is a pre-java5 version of Cocoon.
Ok - this will then be fixed in the first milestone of 1.6.0M1 when we upgrade to a newer version of the Eclipse Compiler.
This should be fixed in the latest AJDT 1.5.2 dev builds for Eclipse 3.3 - available from the dev download site and update site: http://www.eclipse.org/ajdt/downloads/ http://download.eclipse.org/tools/ajdt/33/dev/update This includes AspectJ1.6.0m1
