[Bug classpath/25344] New: FileChannel.lock throws InternalError instead of IOException if no locks available (ENOLCK)

[greenrd at gcc dot gnu dot org]

This is with SableVM version 1.13-pre1, but looking at the source code, the
issue still exists in classpath head.

If the fcntl is unable to obtain a lock (error code ENOLCK), FileChannel.lock
throws a java.lang.InternalError instead of a java.io.IOException. (It is
thrown in the native code in
native/jni/java-nio/gnu_java_nio_channels_FileChannelImpl.c )

I believe InternalError should be used only for JVM bugs, not for operating
system resource failures.
