Mikhail, you comment is perfectly correct, I answered in JIRA - I'll remove
the method addValue() .
I think the problem on Linux is concerned with implementation of JIT helper
- probably there is some unsafe data conversion. I'm still looking for the
root cause. I know many people may beat me for this but the debugging on
Linux is awful.

thanks,
Pavel
