Robert Muir commented on LUCENE-1919:
-------------------------------------
{quote}
Is there any sort of shared state in the analyzing, possibly
between instances that is fixed in this patch?
{quote}
Yes. if for instance you call foo = ts.next(reusableToken), then call bar =
ts.next()
foo will be overwritten by bar in the second call.
this is because it is incorrectly "reused" in next()... see the testcase i
attached for an example.
