Can you please let us know what is the issue here?

Resolution

Please review the following:

SSL and TLS Communications Overview

Note:
SHA2 or SHA-2 is a name for several hashing algorithms, which include SHA-224, SHA-256, SHA-384, and SHA-512. For Web Servers, SHA2 is supported. With a default JRE policy, only SHA-256 is supported. After installation of an unlimited JCE policy, SHA-384 is supported.

In this case the signed certificate that is being used has following algorithm:

Signature algorithm name: SHA1withRSA

This algorithm is not supported with default JRE policy as indicated in the above document.
