Which JVM do you use? How did you install Jenkins?
We also saw similar problems when upgrading from 1.427 to 1.455.
The reason (as far as we could find out) was that *something* removed the
execute privileges on the "plugins" directory. It seemed to happen periodically,
maybe as an indirect result of some of our periodic jobs (we certainly did *not*
change "jenkinsdata/plugins" explicitly!).
Our instance is running under Apache/Tomcat using 1.6.0_18.
Probably as a consequence of that, we got a lot of
"CannotResolveClassException"s
and also marshalling problems, for example:
