CONNECTION_REFUSED for communication between OHS 11.1.1.6 and WLS 10.3.6 after Java 1.7.0_51 install

We upgraded the JDK used by our WebLogic Server from version 1.7.0_45 to 1.7.0_51. We immediately got "Failure of server APACHE bridge:" errors displaying in the browser. The server's mod_wl_ohs logs indicates [CONNECTION_REFUSED] (apr_socket_connect call failed with error=146. We reverted back to version JDK 1.7.0_45 and all was working fine again. I looked at the Release Notes for Java 1.7.0_51 as saw a possible culprit being the changes in the Default Socket Permissions. We're trying to communicate over the WLS port 7003 which probably isn't an ephemeral port. Is it necessary to add grants to the local security policy file
