"Initial Handshake failed" on ssl sessions with 1.3.1

Today I exchanged the quickfix/j library in my fixengine in our test environment with the 1.3.1 version(before 1.3.0).
There are many sessions configured in it; all non ssl sessions came up, but the one that has ssl configured doesn´t:

I switched back to the old library (1.3.0), restarted the fix engine and it works without any problems. the mina core and the ssl-filters havent changed, so it must be something in the quickfix/j core code.
