Yes, it needs care. You cannot call any Java API once the thread has been

Yep. It's delicate.

Clearly. At least, given the way you're using them. Use only one thread
and re-use it instead of creating hundreds of them. Especially since you're
not using them concurrently (at least in the example code you submitted). If
you use just one thread and feed it documents to index via a queue and
notify(), you should get the same effect.
