I profile a test file within IDE in last night, and the morning it completed, then I open profile result window, until now every thing fine (except that all test cases show that they used 0.0s, not the truth). Then I closed my notebook and after 1 hour I open my notebook, this time NetBeans without any response, until now (more than two hours) still no any response.
I tried again, it is very easy to reproduce. Just run a profile test, after complete, close notebook cover, then reopen it, then NetBeans will not works and always no response.
