I cannot reproduce this issue since there is another one blocking me - Issue #176771. I'll evaluate this one once I manage to fix the second.
The blocking issue #176771 has been fixed, but I cannot reproduce the issue reported here.
Is that always reproducible? On what project type? What libraries do you have? Did you somehow fiddled with the project configuration? If you can reproduce, could you please attach the project here or send it directly to me if confidential?
Closing the issue as worksforme, please reopen once you have the answers.
I have not seen it again. I am thinking it may be a side effect of having replaced org-netbeans-modules-web-jsf-editor.jar during testing for 176255 (which I later reverted).
