Can one of the admins verify this patch?

[lyubomir]

Jenkins: it's ok to test.

Note: this would be obsoleted by jitsi/jitsi-universe#5, or rather the version should be removed completely again.

Oh, thank you very much, @ibauersachs! Are you saying that I should merge your PR, then close this one, and remove the bouncycastle dependency from jitsi-videobridge?

[ibauersachs]

@lyubomir Please do in the following order:

1. merge the ice4j PRs. If that is done, I'll publish ice4j 1.0 on Maven Central.
2. merge jitsi-universe#5
3. set ice4j to version 1.0 in jitsi-universe (I can create a follow-up PR for that)
4. update the pinned version of jitsi-universe in libjitsi. Include changes of Update boncycastle from 1.51 to 1.54 libjitsi#72 (except the fixed 1.54 version of BC) to enable compilation again.
5. update the pinned version of jitsi-universe and libjitsi in videobridge and remove the BouncyCastle version (not the dependency).
6. Do the same as in 5 for jicofo, maybe jigasi (haven't looked at that)

Thank you, @ibauersachs! I'll try to do as you said.

@lyubomir Thanks! I updated the comment before to include libjitsi updates.
