Description
I am encountering this problem on and off again only within our Jenkins build environment, I cannot reproduce it locally with the same java and maven version. Also after some code changes not related to SCR annotated classes it works again then it doesn't.
Unfortunately I also was not able to produce a minimum example to reproduce this.
Basically I guess what would already help, is to check against 'null' and log the 'pathToClassFile' that caused the input to be 'null'.
By the way I wanted to do this myself just to get more information what is wrong in my environment, however the http://felix.apache.org/downloads.cgi links for the generator sources return 404...
Here the output on Jenkins:
