AudioSystem.getAudioFileTypes() reports no supported file types




AudioSystem.getAudioFileTypes() should return an array
of file types for which file writers are available on
the system.  Instead, it always returns an array of length
0.  AudioSystem.getAudioFileTypes(AudioInputStream) works
correctly.

Removed from Ladybird project as per request.
Although this bug applies to Ladybird as well as Merlin, there are no engineering resources to address it in the Ladybird project timeframe.

N/A

This problem occurs due to a coding problem in SunFileWriter.java, in 
which the array of supported file types is set to:

     public static final AudioFileFormat.Type types = {};

This types variable is then used in the implementation of getAudioFileTypes()
and, unsurprisingly, always returns an array of length 0.

I have a fix for this bug in my workspace.

The fix is in our standalone workspace, awaiting approval for integration into kestrel or ladybug.

	No engineer to confirm if fix is in. Committing to 
	merlin to properly close this bug.

	Fix confirmed for Merlin.

I have the same problem, is ther a fix around?
please mail it to me
best regards

You complain there are no engineering resources.
This would not be the case if it was open sourced.
Imagine all the bugs that could be fixed.

looks like it is not fixed in jdk1.4 rc0
I have the problem.
Also authorizations in the java.policy for the javasound 
demo are not well recognized. file could be saved (before 
the unsuportedfiletype bug occured) but could not be loaded 
though I made a copy/paste of the grant{} stuff from the 
readme file

Works for me in build 1.4.0-rc-b91:
import javax.sound.sampled.*;
class AudioRes {
  public static void main(String args[]) {
   AudioFileFormat.Type types []  = 
AudioSystem.getAudioFileTypes() ;
   System.out.println("Formats: " + types.length) ;
    for(int i=0; i<types.length; i++)
     System.out.println(i+ ":  " + types[i].toString()) ;
 }
}

Output:
Formats: 3
0:  AU
1:  AIFF
2:  WAVE
