A third-party product issue 
A known issue with IBM JDK 1.6, described in APAR IV37333, was fixed in later versions.


Perform the following local-change to the operating environment: 
  1. Upgrade to JDK 1.7.
  2. Encounter another SSLHandShake exception related to the TLS protocol version where the end-point only supports TLS 1.0.
  3. Bypass Step 8 of the invokeAxis2 activity as described in SA-14558 to resolve the issue in Step 2.
The problem is resolved by upgrading to JDK 1.7.
