      A DESCRIPTION OF THE PROBLEM :
      With build 11-ea+24 a jdbc connection to a ms sqlserver can't be established anymore. The connection is stuck at SSLSocketInputRecord.decode(ByteBuffer[], int, int) line: 169.

      The issue doesn't occur when using build 11-ea+17.

      REGRESSION : Last worked in version 11

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :

      Connection is established.
      ACTUAL -
      Connection locks up. The stacktrace of the lock is:
