Cause
Changes or updates were made to the JVM while Crowd was running. For example, one customer noted they had made changes to the JVM to protect against the Shellshock Software Bug.
Solution
Resolution
If you've made changes to the JVM, restart the applications using that JVM.
If a restart is not possible, it may be possible to revert the changes made to the JVM. Restarting affected applications is the preferred way to resolve this problem.
