I see that the exceptions is shown in the IDE log file but not visible for users.

Should the compiler issue be also created?
Comment 8 Karol Harezlak 2010-05-27 13:30:00 UTC 
In my opinion yes.
Comment 9 Alexandr Scherbatiy 2010-05-27 13:41:04 UTC

----------------------------------

In order for us to fix this bug, we need to be able to reproduce it reliably with a simpler case.  Do you think that is possible?

[Using the stack dump, and looking at the code, it seems either the check instance is not initialized or the warning stack is empty.]
Comment 11 Karol Harezlak 2010-05-28 14:38:16 UTC 
We already provided reproducible case for this issue. For somebody who is in charge of this issue should be relatively easy to find a problem since this bug appears every time you follow provided steps.
Comment 12 Karol Harezlak 2010-06-07 13:16:30 UTC
