Environment
- CloudBees Jenkins Enterprise
Resolution
This is an issue with the plugin. Look at the stacktrace in the logs to determine which plugin.
You have two options:
1) Disable the plugin (if possible) and report the issue on https://issues.jenkins-ci.org.
NOTE: This is the recommended option.
2) Disable JVM bytecode verifier.
NOTE: This is not recommended, as it disables strict verification, which is an important security consideration.
I would read this before considering this option.
If running Jenkins on Java 8, add:
-noverify
If running Jenkins on Java 7, add:
-XX:-UseSplitVerifier
See How to add Java arguments to Jenkins for how to do this.
