I can reproduce in 1.527, same exception. For me it works in 1.400, 1.470, 1.490, 1.495 and fails in 1.500, 1.510, 1.513 and 1.527, so it changes somewhere between 1.495 and 1.500.
It still fails after clearing tomcat/work/Catalina/localhost - is that the cache that you were referring to?
>Could you reproduce this problem after deploying jenkins to other tomcat?
Jenkins works fine on Tomcat with all the latest versions and there is nothing special about the build I'm running, it's a Hello World knocked up in two minutes in Eclipse with an Ant script to build. For me this problem is most probably related to having to use older versions of Tomcat, SLES and hence Jenkins, but I was hoping there might be a workaround so that I could run the up to date Jenkins build.
it works in version 523, broken in 524, 525
