Fixed exceptions in System Log by deleting rogue .jpi file and enabling JavaDoc
plugin.
Will wait and see if that fixes the crashes.

Subject: Our Jenkins instance keeps crashing
Hi
Jenkins is crashing on me several times a day. I am running Jenkins 1.552 on
Centos 5, in a VM. Jenkins used to be stable for us. The only symptom I see is
that my browser shows:
"An internal server error occurred. Please try again later."
I don't know where to start debugging this.
The Jenkins system log has several severe errors/warnings:
