Windows- Native exceptions.



 
Hello All. I have a simple application that tries to play streaming movies from URL. Functionality is the same as "File->Open URL" in the QuickTime Player. Only difference is that I have a reference movie and 4 different speed versions and I download the reference movies before streaming.

At clearly RANDOM times, (and non repeatable), I get one of three exceptions occuring due to different functions/dlls.

-------------------------------------------------------
Exception 1:

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION (0xc0000005) occurred at PC=0x668086E2
Function=DllMain+0x7692
Library=C:\WINDOWS\system32\QuickTime.qts

Current Java thread:
    at sun.awt.windows.WToolkit.eventLoop(Native Method)
    at sun.awt.windows.WToolkit.run(Unknown Source)
    at java.lang.Thread.run(Unknown Source)

Exception 2:

An unexpected exception has been detected in native code outside the VM.

My QT-J methods are essentially :

try {
OpenMovieFile.asRead(...)
movie=Movie.fromFile(...)

movieController.goToTime(..)
movieController.setSelectionBegin(..)
movieController.setSelectionDuration(...)
movieController.setPlaySelection(true)
movieController.prerollAndPlay(1)
}
catch {QTException ..)
{}

Java =1.4.2_07 QT-J 6.1 (cannot upgrade for certain local portability reasons. So, I need to fix these with the above config.) Same exceptions on Java 1.5.0 as well.

Has anyone had these bugs before? Any clues?

Thanks in Advance.
