we have encountered a typical problem with Yellowfin connecting to SQL Server running under ForcedEncryption (in SSL Mode).


Environment details.

Host Operation System : Window 2012 64 bit Operation System.
Yellowfin Version: Yellowfin 7.1
JDK Verison : Java 1.8 (customer had to migrate to this JDK because of their Security regulations, this cannot be reverted).
SQL Server : SQLServer 2012 (running on ForceEncryption), refer to the below screenshot for more details.






While connecting to the SQLServer the following error is getting reported in the JDBC log

Doing some research we found that the problem can be solved by following the steps mentioned in (http://stackoverflow.com/questions/11497530/jdbc-jtds-sql-server-connection-closed-after-ssl-authentication).

All the steps works fine, as long as we are working on JRE7, the moment we change the JRE version from 7 to 8 the following error gets reported in the JDBC log

request to provide a solution with JRE8 as our customer cannot revert back to JRE7 because of security policies.
