Most likely it crashes... Either due to some problem in libefembed.so or in
the JVM itself. Try specifying more heap to JVM...

I run Debian "woody" upgraded to "sarge" (testing version). That was the OS
where libjaybird.so was compiled. Try recompiling libjaybird.so in your
environment (build.sh compile-native).
