Description Andrew Krasny 2011-09-23 14:46:16 UTC 
This is a follow-up bug after Bug 202550 - IDE hangs on start with existing project (http://netbeans.org/bugzilla/show_bug.cgi?id=202550)
The real problem is that getting HostInfo on a Windows host may cause a lock if called before info is available.
Comment 1 Andrew Krasny 2011-09-27 14:54:38 UTC 
fixed in trunk: http://hg.netbeans.org/cnd-main/rev/2e950e09bed1
Comment 2 Vladimir Voskresensky 2011-09-27 16:13:03 UTC 
it might affect windows distribution
Comment 3 Vladimir Voskresensky 2011-09-28 11:09:00 UTC 
I have reviewed the fix. It is safe and correct
Comment 4 Andrew Krasny 2011-09-28 11:27:14 UTC 
Here is a plan we want to propose for QA to test this:

Original issue (202550) was that IDE hangs on start if there were open projects... 
That issue was fixed in cnd.makeproject module and it 'masked' the root cause of the problem. So after that fix everything works, but *this* issue exists. 

Suggestion is to 'revert' the fix of 202550 by substituting makeproject.jar file and see that 202550 is reproducible.
Then get nativeexecution.jar with *this* fix and make sure that 202550 is not reproducible (even without a fix in makeproject.jar).

Fixed nativeexecution.jar is in trunk;
makeproject.jar with 'reverted' fix of 202550 is attached.
