[jitsi-dev] [libjitsi] Latest libjitsi.jar throws DTLS exception while jvb's libjitsi.jar is OK (#16)

01101000 · August 11, 2014, 8:32am

If I use libjitsi.jar copied from videobridge(https://download.jitsi.org/jitsi-videobridge/linux/jitsi-videobridge-linux-x64-202.zip), everything is OK, no exception appears.
But if I use libjitsi.jar built from latest version of libjitsi repo, there will be some DTLS exceptions:
BTW, libjitsi and bouncycastle(bcpkix-jdk15on-151.jar, bcprov-jdk15on-151.jar) have been updated to latest version.

Here are DTLS exceptions:

Did you open this issue for your own bookkeeping purposes or did you actually want a libjitsi developer to look into it? If you want me to work on it, I'll need detailed-enough instructions on how to reproduce it.

I think this was supposed to be in the jirecon issues.

Sorry, it was my fault. I originally thought the problem was related to libjitsi while it actually happened in Jirecon. I'll move it to Jirecon issues.
