Description Jan Becicka 2001-10-09 14:16:06 UTC 
[200110090100]
See stack trace. Exception was thrown, when createFromTemplate() was called.

DataObject dob = getDO ("Templates.Classes", "Class", "java");
DataObject mdob = dob.createFromTemplate(DataFolder.findFolder(getFO
(packageName,null,null)),className);

getDO means get DataObject
getFO means get FileObject

I'll assume this is not reproducible.

The fix to #14179 was supposed to have fixed this kind of problem. It
is still possible that if you are very unlucky, you hit a race
condition where the object is invalidated right before it is used.
There is no way to really fix such things without a loaders mutex
(maybe in 4.0, not before).

If you find this is reproducible, or even that it happens more than
once and is not so rare, please reopen.

Vito, we should consider taking out the invalid check from
getNodeDelegate soon, I have a feeling that even with many fixes
having been made, the check will cause more damage than the root
problem.

Agreed, I see no one reporting such problems in last days, I beleive 
we already fixed most of cases.

Resolved for 3.4.x or earlier, no new info since then -> verified
