That is a great question for java-user at lucene.apache.org [1].
With this topic, whatever answer you find there applies here too.

I should point out, as a reminder of a related issue, that jcc-PyLucene [2] 
does not have the threading problem that's plagued gcj-PyLucene [3] for 
years when used in-process in a web server such as Apache. With 
jcc-PyLucene, one can attach a thread to the Java VM anytime after its 
creation. Look for attachCurrentThread() in [2].
