net.sf.fmj.filtergraph.FilterGraph.SUPPRESS_TRACK_READ is set to itself. I believe it should be set to
net.sf.fmj.filtergraph.FilterGraphProcessor.SUPPRESS_TRACK_READ.
I don't know if it affects anything as only callers I can find are in net.sf.fmj.media.content.unknown.Handler.
Source with change noted.
