I'm a little confused by the question, or maybe the confusion lies in 
how the OpenJDK 7 is part of OracleJDK.  We take the OpenJDK 7 source 
and make some modificiations (adding in some closed code, replacing bits 
here/there, etc.).  So Oracle JDK 7 has had TLS 1.2 since mid-November, 
b114 if I'm reading the logs right.

SHA-1 can still be used as the basis of MACs which is where it's used a 
lot in TLS.  It's SHA-1 by itself that is of concern.
