Cannot change default port from 8081 to custom during maven install of quickstart example switchyard-transform-xslt.

• Testing quickstart example switchyard-transform-xslt.
• When I run maven install command during Test class execution I am getting below exception. I cannot change port 8081 which is already used by some other program in my windows system.
