Hi Oleg,

Without knowing what version of JIRA you're running, from the stack trace you provided it appears you may be running into the bug reported in JRASERVER-62486. 

Please take a look at the JRASERVER-62486 and review the description and the work around and see if that is the solution for this issue.  If so please vote on JRASERVER-62486 and you'll be notified when there are any changes to JRASERVER-62486.

Cheers,

Branden

Besides the bug mentioned by @Branden McElveen (JRASERVER-62486), another possible cause for the error above would be the conflicting system JAVA.

To properly diagnose and work around this problem, you can follow the details of the documentation below:
