Description

Considering a highly multithreaded system, where threads have a short living
time, and some of the threads perform XSLT transformation, but only once, the
JVM soon reaches memory saturation, since XMLReaders are never re-used.

I would suggest maybe to keep the ThreadLocal mechanism instead of the map +
ThreadLocal duet which appears redundant to me, but maybe i am missing some point ?
