What MySQL jar are you using?
What MySQL version are you connecting to?
What Java version are you on?

Evry things was worked well but when I updated logstash to5.6 this crash happend. i removed this version and installed previous version 2.4 now its ok

If I remember correctly logstash 5 requires a different version of java. So you should've updated java and changed your MySQL jar.. If you didn't do that it may explain your issue.

I know MySQL works because it's included as part of the test suite.
