Java_org_classpath_icedtea_pulseaudio_Stream_native_1pa_1stream_1cork: Assertion `operation' failed

[Johannes Drummer]

When I run the game mojam from humblebundle.com I get the following error message. The error occours after several seconds after start. The game definitly works under windows, so I guess it is a bug between openjdk and pulseaudio.

Note, this happens with openjdk 6 and openjdk7
openjdk-6-jre 6b24-1.11.1-0ubuntu1
openjdk-7-jre 7~b147-2.0-1ubuntu2
Ubuntu 12.04

java -jar mojam.jar

Hi,

Same problem here on 11.10, 64bit.
I get the same messages as Johannes.
The game is successfully playing audio even while printing the "unable to prepare stream" errors, but asserts when I shoot.

I am seeing this with Ubuntu's openjdk-6-jre Version: 6b23~pre11-0ubuntu1.11.10.1 and also with Debian's openjdk-6-jre Version: 6b24-1.11.1-1 (also 64bit, unstable repo).

[aihtdikh (aihtdikh)]

submitted to debian bts too

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Johannes Drummer (johannesdrummer)]

If I run with oracle jre 1.6.0_31, i get the following stack trace too and I don't have audio, but the game doesn't crash.
