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

It sounds like you are simply demonstrating an old bug, right?  If so, then=
 we can close this issue, since LUCENE-1346 fixed the bug you described (I =
didn't verify that).

> 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 e=
quals method.   In a concurrent environment a deadlock might occur.    The =
attached code example shows this happening in lucene 2.3.2, but the patch i=
n LUCENE-1346 fixes this issue (though that doesn't seem to be the intentio=
n of that patch according to the description :-)
