Has anyone recently (like a few days) had fatal problem recording sounds with AudioRecorder?

I'm using it in a big project, it was working fine a few days ago but now nothing.

Even the example that comes with Processing "RecordingLineIn" is not working.
The problem is in the save method. I get the exception message

1. java.lang.IllegalArgumentException: invalid output index: output.length=163840 outByteOffset=2 sampleCount=40960 format=10: 16bit signed little endian

If run on Eclipse it gives more detail:

1. Exception in thread "Animation Thread" java.lang.IllegalArgumentException: invalid output index: output.length=163840 outByteOffset=2 sampleCount=40960 format=10: 16bit signed little endian

Also I'm running a Mac (might be important).

I really don't know what to do. I've run in with a similar problem when I was using a external microphone and I forgot to put batteries on it but now I using the internal one so I'm totally lost
