Description Andrew Clement CLA 2014-09-17 13:43:00 EDT 
import org.aspectj.lang.annotation.*;

@Aspect
public abstract class Bottom extends Middle {
}


import org.aspectj.lang.annotation.*;

@Aspect
public abstract class Middle extends Top {
}


public abstract class Top {
}

gives:
java.lang.NullPointerException
	at org.aspectj.ajdt.internal.compiler.lookup.EclipseSourceType.getPerClauseForTypeDeclaration(EclipseSourceType.java:1034)
Comment 1 Andrew Clement CLA 2014-09-17 13:53:48 EDT 
There is an order to compilation required here too, to trigger the error:

"Bottom.java Middle.java Top.java"
Comment 2 Andrew Clement CLA 2014-09-17 13:54:18 EDT 
Fix committed. I guess the guess of annotation style aspects extending regular classes just hasn't come up before.
