Hi Jean-Frederic,
I like your patch. Thanks for your help. :-)
I'm also wondering why we dlopen libjvm.so in the first place ?
After all, on my linux machine I had to specify the location
of libjvm.so and other JRE .so files via LD_LIBRARY_PATH anyway
(otherwise I would receive a JVM init error while the VM was trying to
load other JRE libraries).
So, if the user has to specify the LD_LIBRARY_PATH to get everything
to work anyway, why not dynamically link jsvc against libjvm.so in the
first place ? This makes things much simpler and removes the need to
calculate which VM to use and where it is, and lets the user change it
via an environment variable ?
I'm interested in everyone's thoughts for and against ?
Cheers,
Marcus
