WebLogic Server exceptions while connecting to external applications over SSL, HTTPs

WebLogic Server 10.3.5 exceptions while connecting to external applications over SSL

Exceptions examples:

java.lang.ClassCastException: weblogic.net.http.SOAPHttpsURLConnection

javax.xml.ws.WebServiceException: javax.net.ssl.SSLKeyException: 
[Security:090550] The certificate chain received from ...
contained a V3 CA certificate which indicated a certificate 
chain path length in the basic constraints that was exceeded.

This is caused by an incorrectly ordered certificate chain sent from the third party server or load balancer.

Workaround: 

Enforce WebLogic Server to use SUN SSL implementation. Add -DUseSunHttpHandler=true  to JVM arguments.

In Admin Console navigate to Home –> Summary of Servers –> <managed server name>, Configuration > “Server Start” Tab. Add –DUseSunHttpHandler=true to “Arguments” section. Restart Managed server(s).

Solution:

The solution to this is to contact the third party vendor and request them to reorder their certificate chain to comply with the TLS 1.2 specification.
