###@###.### 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.

SUGGESTED FIX Getting rid of PluginJavaInfo, finally. We (Andy, Ken and I) have discussed this before weeks and agreed that we can use the unified version. This simplifies the Config/JREInfo code, the UI of the control panel, etc.

EVALUATION Indeed, the complexity of PluginJavaInfo and JREInfo 'collaboration' were responsible of the loss of the vm-args.
