Build : 'F' (worked in beta-'N')
OS : Solaris only (Win32 ok)
app : Java2Demo.jar (must run -ccthread cmdline option)

When Java2Demo is stressed by running the -ccthread or the Menu item Custom Control Thread option. This particular media: sfx-medley.rmf seems to get starved of process in addition to playing incorrect instruments on playback of that .rmf file.

Simply run: java -jar Java2Demo.jar -ccthread
then goto the Mix tab and play the sfx-medley.rmf file.
