It seems this problem only occurs for "Struts 2 Webapps" module [1]. I tried to verify this in Jenkins but I didn't have access to configs. I also tried a PR but forgot that PR doesn't build against JDK6. So could you please verify if jdk6 starts working via deleting this module in Jenkins configs? This makes us more near to answer what's the problem with. Before these, you may also try compile with Jenkin's /usr/lib/jvm/java-6-openjdk-amd64/ [2] to see if makes any difference or info. Regards.
