Comment 5 Svata Dedic 2014-03-21 12:46:52 UTC

Cause by Lombok; some inserted tree parts do not have positions. The code in question attempts to alter source to ensure the result will resolve correctly - I can make the issue less irritating by pretending the alternative call would be ambiguous which would suppress the hint, but at the same time may leave some situations unnoticed.

More elaborate fix (which could be done later) could involve pretty-printing part of the source tree possibly generated by Lombok and reparsing it back.

Leaving open, exception should be avoided by jet-main#b8199830f4b9
