I don't know what information you need to reproduce this, but here is what I have noticed:

In a local repo where I have previously done a "make images", if I change the source code, and do a "make images", it does not update "build/<platform>/images/jdk/lib/src.zip" with the latest source code changes.

It seems to just copy "build/<platform>support/src.zip" which is also not up-to-date. I have also tried doing a "make zip-source" beforehand but that doesn't seem to update "support/src.zip" with the latest changes either.

This was on macosx-x64. Let me know if you want me to attach any build logs.
