There's been a couple of followups points that I won't repeat:

There is no difference in the Oracle and OpenJDK JSSE implementation. 
They are the same.  That said, other distributions which derive from 
OpenJDK (e.g. IcedTea or Linux distros) may have differences, but that 
is outside my knowledge area.  If you build OpenJDK from the source, the 
binaries of JSSE in OpenJDK and OracleJDK will be the same.
