I cannot reproduce this bug on Windows 7 (NB Dev 201408180001, JDK 1.8.0_05 64 bit).

Does the bug occur randomly, or every time you try to open Help Contents?
Can you reproduce the issue with another version of JDK?

Thank you.

Comment 3 soldatov 2014-08-22 14:23:15 UTC

Randomly. I didn't this exception from that time.

Comment 4 Jaroslav Havlin 2014-09-05 10:46:41 UTC

I cannot reproduce this bug on Mac as well.
I'm sorry, I have no idea what could have caused it.
(A race condition or a bug in swing maybe?)
Closing for now. Thank you for understanding.
