I am re-compiling Apache Spark for RPI2 and I've spent a couple of days to fix the issue. Then I've found the easiest possible solution. All you need to have is a libjnidispatch.so link in your default JVM's native lib path.

sudo -s ln -s /usr/lib/arm-linux-gnueabihf/jni/libjnidispatch.so /usr/lib/jvm/default-java/jre/lib/arm/libjnidispatch.so
