Hello,
I found a much easier to detect the path to JAVA_HOME on Unix-like
platforms where the java command is in the search path. java -verbose

Hello,
I've developed a small helper package for JCC to monitoring the embedded
JRE. It constructs a SSH-tunnel friendly JMX connector.
With JMX you can monitor all sorts of stuff like memory usage, CPU
usage, threads, loaded classes etc. With jvisualvm you can even profile
your application,

There shouldn't be any random threads. Threads don't just appear out of thin

I've already made sure, that all our code and threads are calling a

If not, then that could be an answer as to why this wasn't noticed before.

Presumably that's no longer the case with JCC 2.6. Probably should be
updated to whatever the current version does. Or perhaps versioned and
checked into the source tree.
It could be related to the --no-generics addition. Have you tried to
recompile PyLucene with the option JCCFLAGS=?

The Makefile has about a dozen sets of defaults for a variety of platforms.
Pick the one closest to your setup, uncomment it (and change it if needed).
Then you don't have to enter these on the command line.
