Re: [aspectj-users] AJDT throws NullPointerException after adding cflow.
|
Raised and fixed as https://bugs.eclipse.org/bugs/show_bug.cgi?id=314766
Please raise bugs for NPEs, they should never occur and indicate a real issue.
Next refresh of AspectJ into AJDT (which will make this fix available
in AJDT) should happen in the next couple of days.
