Description Lambert Busmann CLA 2011-07-24 09:35:24 EDT 
Eclipse Indigo AJDT 2.13

When editing a aj-file, i receive the folloing exception

java.lang.NullPointerException
at org.aspectj.weaver.bcel.BcelClassWeaver.addInitializer(BcelClassWeaver.java:247)

end abstract class ...


Short time before, two projects have benn added to the inPath of the project and, because it is a maven project, to the pom.xml. 

in the aj-file a parent is declared implementing a interface.
   declare parents: INode implements IBlueprintItem

Both INode and IBlueprintItem are interfaces. 

The aj.file is attached to this bug.

Comment 2 Andrew Clement CLA 2011-07-25 16:31:38 EDT 
Does this keep happening?  Or was it just a one off occurrence?
Is INode a generic type?

the corrected version
Comment 4 Lambert Busmann CLA 2011-07-27 05:14:31 EDT 
INode is a generic type (Inode<VC, EC, E extends Enum<E>>):

the newly attached file works. The difference is that the declared methods now are bound to INode and not to IBluePrintItem.
