Hi,
the attached program segfaults. gdb shows:

where everything is of the latest (unstable) debian on linux / i386.
The strange thing about this is, that the program segfaults also when using
blackdown's java and linking their libs. I'm beginning to think that
JNI_CreateJavaVM() don't work at all ;-)
Well, is my program the problem, or is it the implementation of
JNI_CreateJavaVM() ?
Any help much appreciated.
