[aspectj-users] A strange error (ExceptionInInitializerError)

Manuel Menezes de Sequeira Tue, 08 May 2007 02:55:48 -0700

Hi,

I have a project consisting of the following files:

InvariantEnforcementApplier.aj

public aspect InvariantEnforcementApplier extends Enforcer {
}

Enforcer.aj:

public abstract aspect Enforcer {
after(): !cflow(within(Enforcer)) && execution(public *.new(..)) {
}
}

Test.java:

public class Test {
//   Test() {
//   }
    public static final void main(String[] args) {
        Test r1 = new Test();
    }
}

Executing Test.main results in:

Exception in thread "main" java.lang.ExceptionInInitializerError
    at Test.<init>(Test.java:1)
    at Test.main(Test.java:4)
Caused by: java.lang.NullPointerException
    at Enforcer.<clinit>(Enforcer.aj:1)
    ... 2 more

Removing the comments from Test's constructor, the exception is not longer thrown. This looks a lot like a compiler bug.

Thanks a lot for your help,

Manuel
