Cannot use Open Source license after evaluate

When I change my license from evaluation to Open Source, I can't to find or create Issues. If I return eval license back - Jira starts to work.
NOTE: I use Professional version, I've double check this.

For example when I try to find I have:

Errors:
An error occurred searching: java.lang.reflect.UndeclaredThrowableException
An error occurred searching: java.lang.reflect.UndeclaredThrowableException

From application server log:
