Below is the crash report from the JVM / CoreAudio
crash. Starting any java based IO Proc results in a crash. From
the call stack it on the crashed thread, shown below, seems that execution does
not even reach the AudioDeviceIOProc in java, which is empty and could not be
the source of the crash anyway. The crash reproduces on either Java 1.4.2
or Java 1.5 on the Intel based Mac. Any insight on how to use a CoreAudio
IO proc without crashing would be much appreciated.

Subject: CoreAudio.jar, AudioDeviceIOProc and
ADevicePropertyListener
My java app uses the CoreAudio API via CoreAudio.jar and works perfectly
on
PPC. However, on Intel, the application crashes whenever my code
gets a
callback from CoreAudio for an IOProc (audio capture) or a property
listener
(volume change)
Forward method calls from java continue to
work perfectly on both platforms.
It is only the callbacks that blow
up.
Am I right in expecting the CoreAudio API to work the same (via Java)
whether on PPC or Intel?
Any advice on how I can modify my code such
that callbacks on the following
interfaces work on both
platforms?
com.apple.audio.hardware.ADevicePropertyListener;
com.apple.audio.hardware.AudioDeviceIOProc;
Thanks,
Bryan
