test env: jre8 b29, 32bit winxp

steps to reproduce:
1)enable java console
2)launch the following 2 apps
http://rehte.cn.oracle.com:8080/wshost/new_framework_exe/new_framework/tests/javaws/jawsService/jnlp/red_href.jnlp
http://rehte.cn.oracle.com:8080/wshost/new_framework_exe/new_framework/tests/javaws/jawsService/jnlp/red_href2.jnlp
The 2 jnlps are different, but both of them point to red_href.jnlp in href.
The first app adds a single instance service, in the java console, we can see

MultipleLaunch newActivation() called....
MultipleLaunch NEW-ACTIVATION BLUE

It means when launching red_href2.jnlp, though it uses the main calss in red_href.jnlp, but passes the arguments in red_href2.jnlp to it.
