Description helmutpozimski 2008-06-22 15:32:20 UTC
I compiled the latest svn-sourcecode of cortado using the Java 6 SDK supplied by the Debian repositories. Compiling works fine but after that it is not possible to play a video. Cortado buffers, starts playing and stops with messages like that:

Again, with Java 5 (aka 1.5) everything works fine. 

Im am using a Debian lenny system, amd64 architecture and Java 6 update 6
Comment 2 Tim Starling 2008-07-02 04:46:37 UTC
bd1_pp.ogg works just fine on my 32-bit system. If someone could confirm this on a 64-bit system, that would be handy.

Have you tried using the precompiled jar file that we distribute with OggHandler?

<http://svn.wikimedia.org/svnroot/mediawiki/trunk/extensions/OggHandler/cortado-ovt-stripped-wm_r31776.jar>
Comment 3 helmutpozimski 2008-07-02 12:52:24 UTC
Yes, I tried it as well and it shows the same messages and doesn't work either on my system.

Comment 4 Tim Starling 2008-07-03 00:47:13 UTC
Confirmed under QEMU.
Comment 5 Tim Starling 2008-07-03 05:55:06 UTC
The problem appears to be the background compilation feature of JVM, not the architecture. I reproduced it in 32-bit mode and found it to be dependent on JVM options:

works:   appletviewer -J-client test.html
broken:  appletviewer -J-server test.html
works:   appletviewer -J-server -J-Xbatch test.html

Apparently if you're on a 64-bit architecture, it always uses the server VM. 

I've submitted this to the Java bug tracker, now waiting for review ID 1284931.
Comment 6 Matt Ingenthron 2008-07-31 17:02:12 UTC
A bug against the compiler has been filed under 6732194.  This should be posted to http://bugs.sun.com shortly.  Any updates on the bug should be visible there.  It's currently in the queue for evaluation.
Comment 7 Tim Starling 2008-08-06 14:49:58 UTC
I've applied the workaround suggested on the Sun bug report, updated the jar in OggHandler SVN, and deployed it on Wikimedia. It works for me with -J-server, I assume it works on 64-bit too. My thanks to Matt for getting this to the right people. 
Comment 8 helmutpozimski 2008-08-06 15:15:33 UTC
I compiled it myself and I can confirm it works now even on 64-bit. Thank you very much for your great work.
Comment 9 Matt Ingenthron 2008-09-12 17:15:16 UTC
The bug has now been fixed in OpenJDK/JDK 7 development, so once it's mainstream, the workaround should no longer be required.  It shouldn't hurt anything to have the workaround in there though.
