JRE 7 With SSL Connections Generate a: "SSLException: Received fatal alert: illegal_parameter"

On R12.1.3, unable to launch forms after deploying JRE (JRE 1.7.0_21  Native Plug-in) when using SSL configured on Web server level with Load Balancing.
Forms work fine with 1.6.31 JRE, but the Java Console shows:

network: Connecting https://<HOST>:<PORT>/OA_JAVA/oracle/apps/fnd/jar/fndformsi18n.jar with proxy=DIRECT
network: Connecting http://<HOST>:<PORT>:8021/ with proxy=DIRECT Received fatal alert: illegal_parameter

see this same error for the other jar files.

The end of the java console shows:

1. If the LB and SSL are removed, JRE 1.7.0_21 works fine.
2. If adding the LB back, without SSL and it works fine.
3. When adding the LB and SSL, now the issue is occurs.
4. As documented in note: Deploying JRE (Native Plug-in) for Windows Clients in Oracle E-Business Suite Release 12 (<Document 393931.1>), have applied (32-bit) version of <Patch 6370967> - 'TLS 1.0 handshake fails when the client is running on Vista' applied to the AS 10.1.3 Home, as well as the latest forms bundle <Patch 14825718>.
5. Relinked client_sharedlib as documented in note: After Java Upgrade 7 Forms Are Not Opening (<Document 1575167.1>)
6. Made sure that TLS v1.0 and SSL v3.0 are checked in the java Control Panel (Java -> Advanced (tab)) as documented in note: Enabling SSL in Oracle E-Business Suite Release 12 (<Document 376700.1>)

The issue still occurs with the above changes.


Upgrading to JRE 1.7 as documented in note:
Deploying JRE (Native Plug-in) for Windows Clients in Oracle E-Business Suite Release 12 (Doc ID 393931.1)
Upgrading OracleAS 10g Forms and Reports in Oracle E-Business Suite Release 12 (Doc ID 437878.1)
