If an attempt is made to connect with compression enabled, e.g. with Smack
then the connection fails. Disabling compression allows the connection to succeed.
Further notes;
This fails with MINA 2.0.20 (current version on master at the time of writing) and 2.1.0, succeeds with MINA 2.0.7.
Logs from Openfire;
Logs from the XML Debugger:
After much trial and error, it seems that MINA 2.0.13 works with compression enabled, MINA 2.0.14 doesn't.
Seems to be caused by a change in MINA - more information at http://mail-archives.apache.org/mod_mbox/mina-dev/201903.mbox/%3CCA%2BGjePVToJ1hzFDTy50BwpEY1AFjPea%2BETKe%3DLEooHbwfrekTA%40mail.gmail.com%3E
Now confirmed to be a bug - https://issues.apache.org/jira/browse/DIRMINA-1101
Update; the mina-write-branch mentioned in DIRMINA-1101 fixes this issue; now to wait for a release so we can more easily incorporate it.
I've tested this locally and compression is now working with the 2.1.1 MINA release.
