(If JLayer returns without playing SHOUTcast stream then it might mean that the server expect a winamp like "User-Agent" in HTTP request).

Is there a way to pause the music playing?

I read the source code of javazoom.jl.player.Player, but I can't find a way to pause the music playing

If there's a way to pause or skip some frames?
Thanks

Is it safe to use?

In original JLayer there is RCE vulnerability when reading audio data from untrusted source (i don't know details) is it patched here?
