today i try to find the reason for this problem and it seems the problem
totally vanish:-) which is a good news since we can use it, but a bad
news since nether gstreamer-java nor jna packages change since the
problem occurred (may be other packages).

This is a bit of a stab in the dark, but check that the rpm build for
libffi has -DFFI_MMAP_EXEC_WRIT in CFLAGS for the build.
gst_object_unref() will do a C -> java callback, and if you're on a
system that disables the execute bit on normal malloc data (which
should be all of them these days), JNA callbacks will cause the jvm to
crash if libffi is not built to allocate the closure trampoline in
executable memory.

What's in this file? The JVM is most likely crashing due to something
wrong in the JNI code.
attached.
or should i've to package the jna provided by gstreamer-java or
reuild the original jna and not use the fedora one?
This would be against the Fedora Packaging Guidelines.
ok but currently the situation is:
- not working with the jna in fedora,
- working with the jna bundled with gstreamer-java,
- working with the jna download from jna homepage.
so dare i assume there is some problem with the fedora jna package?
