Which parsers do you using?

Can you please attach the scanned log file?

Which JDK are you using?

Used parsers can be find out attached "screen shot" picture. It mainly check warnings from the output of the console log, which is also attached as an zip file. The doxygen warnings log file semas to be empty, e.g. it's size is zero.

Log:
JENKINS-7178 Added test case that exposes JDK bug.

This seems to be a JDK bug, see reference URL. The problematic parser is the Doxygen Parser. Until this is fixed you need to remove that parser.

Integrated in Hudson Plug-ins (Compile) #38
JENKINS-7178 Added test case that exposes JDK bug.

When I use same Warnings parser for a Doxygen log file, that has content it doesn't crash at all. But in my case the content of the Doxygen log file is empty (zero bytes)?
