#205319 : deadlock while expanding servers node

http://netbeans.org/bugzilla/show_bug.cgi?id=205319

Impact : This issue is triggered under very constrained conditions and 
was due to changes to address 
http://netbeans.org/bugzilla/show_bug.cgi?id=184674.  The changes that 
made this hang possible were checked into the trunk in early June.   
This appears to be the first time this deadlock has happened to a user.

Risk: There is low risk that the deadlock will occur (even if the fix is 
not pushed into release71).  The risk associated with getDomainsRoot() 
returning a value which is not yet a complete domain is very low.

The change info is in the issue.

The peer review is in the issue.
