           Summary: NPE while trying to inline pointcut
           Product: abc
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal

In compiling atrack, I get the exception:

Exception in thread "main" polyglot.util.InternalCompilerError: NPE while trying
to inline setAttrib(...) with context aspect org.atrack.policy.SessionTracer

The pointcut itself is quite complicated:

    private pointcut setAttrib(HttpSession session, String name, Object value) :
        (call(void HttpSession+.setAttribute(..)) ||
        call(void HttpSession+.putValue(..))) &&
        target(session) && args(name, value) && scope();

Where scope() is:
    abstract protected pointcut scope();

Specifically, in SessionTracer, it is:
    public pointcut scope() : AtrackExecutionTracer.scope();

In AtrackExecutionTracer, it is:
    public pointcut scope(): within(org.atrack..*);

Please let me know what other information is needed to diagnose this.
