SSL Error while Running Test Case from Java but works perfect in Soap UI Tool

Hello,

 

I am using TestRunner from Java run SoapUI Test Case, which is working perfectly through SoapUI, however while running with Java I get SSL Exception, please advise.

 

Below is code:
TestRunner runner = testCase.run( new PropertiesMap(), false ); 

 

Below is the exception of SSL:
