      Since 4.15, our builds fail due to NPEs in hudson.plugins.warnings.WarningsResult.java, line 108, as "group" is null.

          Sorry, I should have done this when filing the bug. Here is the stack trace:

          Ok, thanks. That helps to fix the bug. Seems that your server had not much memory left, so in the end Jenkins tried to reload the warnings (which are actually not written to disk anymore).

          Hallo Ulli,
          The server in question has plenty of RAM and the issue may happen right after Jenkins startup, so I guess there's nothing to do with memory management.
          BTW, we had to revert to warnings 4.13, as warnings 4.14 have the same problem as 4.15:
