Description Gaël Renoux

Build Identifier: 20100617-1415

When I compile my AspectJ project, I get an AspectJ Internal Compiler Error. The stack trace is : 
java.lang.NullPointerException
at org.aspectj.ajdt.internal.core.builder.AjBuildManager.findOutputDirsForAspects(AjBuildManager.java:725)
at org.aspectj.ajdt.internal.core.builder.AjBuildManager.writeOutxmlFile(AjBuildManager.java:652)
at org.aspectj.ajdt.internal.core.builder.AjBuildManager.performBuild(AjBuildManager.java:367)
at org.aspectj.ajdt.internal.core.builder.AjBuildManager.batchBuild(AjBuildManager.java:181)
at org.aspectj.a ... on$1.run(GlobalBuildAction.java:179)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)

I digged a bit and looked into the classes. It would seem that AjState.getAspectNamesToFileNameMap() can return null in AjBuildManager.findOutputDirsForAspects. It is taken in account when AjBuildConfig.getCompilationResultDestinationManager() returns null or a list with one element, but not when it returns a list with several elements.

Reproducible: Always

Steps to Reproduce:
Always happen in my configuration, but I didn't try to make it happen again in another workspace. Here are the steps I followed.

1. Generate a AspectJ project with Maven using the pom.xml I'll join
2. Create an aspect with a few pointcuts and a few advices
3. Compile (not with maven, the Eclipse compilation)
