Regression: command-line arguments from Java Applet Runtime Settings are being lost

###@###.### pointed out that command-line arguments specified via the Java Applet Runtime Settings in the Java Control Panel are being lost. This can be confirmed by specifying a system property like -Dsun.java2d.noddraw=true in the control panel, runnng any simple applet, and dumping the system properties in the Java Console. Command-line arguments specified via the java_arguments applet parameter or via JNLP are apparently working fine. This is likely a side-effect of the recent changes to merge the JREInfo with the PluginJavaInfo. It is a significant regression because it will prevent the effective debugging of applets (-Xdebug is an insecure command-line argument and needs to be specified via the Java Control Panel so it will be treated as a trusted argument) as well as prevent certain legacy applets from working as expected.
