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

Yes, it can be closed.

I didn't find the bug anywhere in JIRA so thought it was good to have it 
documented since it affected the last official release.



> Deadlock for some Query objects in the equals method (f.ex. PhraseQuery) in a 
> concurrent environment

> Some Query objects in lucene 2.3.2 (and previous versions) have internal 
> variables using Vector.   These variables are used during the call to the 
> equals method.   In a concurrent environment a deadlock might occur.    The 
> attached code example shows this happening in lucene 2.3.2, but the patch in 
> LUCENE-1346 fixes this issue (though that doesn't seem to be the intention of 
> that patch according to the description :-)
