GCJ ------ file type not supported by system

[kgy]

Hello,

I create a native exe for windows by Cygvin.gcj v4.8.3. This ended 
perfectally.  And when I like to run, than exe start and run to the point 
where I like to write to output a sound stream with the "Audio stream with 
the javax.sound.sampled.AudioSystem.write(...)" method. 2nd parameter of 
this method is "AudioFileFormat.Type.WAVE".  This parameter gives the type 
of output sound file. And at this point crashes the program with the next 
error message:

java.lang.IllegalArgumentException: file type not supported by system
   at javax.sound.sampled.AudioSystem.write(Unknown Source)
   at com.all.smws.speech.SpeechFilter.genSliceFeat(Unknown Source)
   at com.all.smws.speech.SpeechFilter.getAnnotations(Unknown Source)

   at com.all.smws.speech.SMWS.getSpeech(Unknown Source)
   at com.all.onins.oi.stream.OnlineInputStream.run(Unknown Source)
   at java.lang.Thread.run(Unknown Source)

Please, help me someone with any words about why. The command line, which 
generates the exe in Cygwin

gcj -fjni -mwindows --main=com.all.onins.oi.OnlineInputStub 
./Jars/sndsep.jar ./Jars/sns.jar ./Jars/smws.jar ./Jars/onins.jar -o 
onins_noopt.exe

Best regards
