Hi Alexander,
VLM methods in JVLC should throw exceptions just like other JVLC
methods. The current implementation throws exceptions away, but if you
need exceptions now you may consider using
org.videolan.jvlc.internal.LibVlc.libvlc_vlm_* methods which fill the
libvlc_exception_t class correctly.

The best would be to check the status of the libvlc_exception_t class in
VLM.java and throw the VLCException accordingly.  Any patch will be
kindly accepted ;)
