In this case the method java.nio.FileChannelImpl.lock() is just not correctly
implemeted and just throws an exception saying "not implemented". Just noone
did it yet. I have some prelimiary code for GNU classpath written in JNI for
this. Perhaps kaffe will simply merge ant dont write its own KNI version.
