> Aparently, Drools builder is attempting to build a file that has moved but has an editor descriptor that no longer exists because the underlying DRL was moved to another package.
> The workspace.xml has an <editor/> entry that still refers to the old package, and Drools Eclipse is trying to build it.
> There may be other problems and workarounds due to this.
