Bryan Pendleton commented on DERBY-6771:
----------------------------------------

client, as the message suggests?
> Derby is crashing and writing
> org.apache.derby.impl.drda.DRDAProtocolException: Execution failed because of
> a Distributed Protocol Error: DRDA_Proto_SYNTAXRM; CODPNT arg = 0; Error
> Code Value = 3. Plaintext connection attempt from an SSL enabled client?
