Comment 2 Dusan Balek 2012-10-19 10:24:23 UTC

EjbFacadeWizardIterator should pass the correct number of type arguments to Types.getDeclaredType(...) call.

Comment 3 Martin Fousek 2012-11-15 14:05:35 UTC

David are you able to reproduce this issue?

wc.getElements().getTypeElement(abstactFacedeFQN) didn't resolved TypeElement although this element (class) must exist - that's something which should never happen. I discussed it also with TomasZ and when the file wouldn't be scanned yet, it should fallback to listing package directory to find the class ... it's weird and could be some underlying issue (maybe in filesystems).

Since I'm not able to reproduce (when you will not be able too), I suggest that I would try to wait until scanning will be finished and add few additional defensive changes which could help and for sure I would also add some additional logging.

Comment 4 David Konecny 2012-11-15 19:14:54 UTC

If you cannot reproduce it I would ignore it. There are only two exception reports after all. Perhaps this is P4 or TM=Next.

Comment 5 Sergey Petrov 2012-11-15 20:14:53 UTC

in my opinion this one issue, issue http://netbeans.org/bugzilla/show_bug.cgi?id=221773 and number of similar may have the same cause. all have somehing just generated but isn't parsed properly and failed to be resolved.

Comment 6 Martin Fousek 2012-11-16 13:12:32 UTC

You are right Sergey, that's similar case.

I added more logging information in web-main #34c1a22c2831 as well. Let's wait what could be broken there. I'm closing this issue since new one will be raised once anybody crossed these troubles since the logging is with the SEVERE priority. The new issue will be reported probably quite differently since I'm doing those check in advance to prevent reporting to Java/Compiler component next time.
