Spark 2.5.4 crashes on Mac OSX 10.4 as soon as voice chat starts

Launch OSX version of Spark, log in, chat with other users, all is fine. Start a computer-to-computer voice chat, accept on other end (or vice versa, doesn’'t matter who initiates) wait for negotiations to proceed, then when it appears that voice chat should start, boom - JVM exits with native java error.

Yes, it says capture device in use or whatnot, but a full JVM crash? ouch…

I’‘m getting this error on my MacBook Pro as well. Strangely, I’'m not getting it on my G5.

Same issue here(with Spark 2.5.6) Intel -> crash, PPC -> works

I’m using OSX 10.4.10 with Spark 2.5.6 and it crashes in the same way as described in the OP. Using a macbook pro (Intel).

Same on 2.5.7 (Intel)

I too am having the same problem. I am running 10.4.10 on a Macbook Pro (intel) with Spark 2.5.7. In fact my luck with voice chat on the last few versions of spark has been pretty dismal. I don’t know if this is related but I also have a problem with the skinned versions of spark not working with Intel Versions of Mac OS X - they just crash on launch . Can someone from Jive please comment on this. If you would like more info I am more than willing to provide any necessary information.



Same here; trying to run Spark 2.5.7 on a Mac Mini running OSX and it crashes when someone attempts to initiate a voice call.

I’d love to have this feature in Spark – what can be done?

(Edit: It’s an Intel processor)

Same here, Spark 2.5.4 on Mac, Funny thing the PC client is unaffected!? I wish I could connect iChat to PC Spark client for the voice… But I think that is a pipe dream.


Just to keep this important bug alive, this is still happening. I have OSX Spark 2.5.8 crash immediately after connecting from a Windows client with Spark 2.5.8. Maybe a problem with Jingle?
