-classic (version 1.2.2 and 1.3)
Use the -classic command-line option to run your application without the HotSpot

command line. The Classic VM is not supported on SDK 1.4 and JDK 5.0.

and -Xcomp modes are supported.
-Dhpux.font and -Dhpux.font.dpi (version 1.2.2 and later)
To change the system font size of your Java™ application when it is launched, invoke
Java™ with the command-line option -Dhpux.font.dpi=[75|100] or
-Dhpux.font=small_fonts.
-Dhpux.im.disable (version 1.2.2 and later)
This Java™ command-line option is a workaround to allow Menu Mnemonics to work.
