Ulli Hafner added a comment - 2011-05-19 07:29 Hmm, seems that some classes are not transferred to the slave. Which version of the findbugs plug-in are you using?

Stephen Kinnison added a comment - 2011-05-19 14:43 The Findbugs plug-in version is 4.22.

Ulli Hafner added a comment - 2011-06-15 08:16 Is Jenkins deployed in a container? (Maybe this is related to JENKINS-9815 )

Stephen Kinnison added a comment - 2011-06-15 12:51 Jenkins is deployed in a Tomcat 6 container. I have been able to get a small project (less than 10,000 lines of code) to run FindBugs on a slave and report back to the master. My larger projects (greater than 20,000 lines of code) fail to report back.

voorth added a comment - 2011-06-29 14:38 After upgrading to 1.418, I'm getting the same error. Strangely, reverting to 1.417 solves it, which is strange, since this issue is older than that...
