Update debug logging (#2719)

my thought here is that JAVA_OPT and JAVA_OPTIONS are just conventions
that some app servers use to populate the command line args, so those
should show up in "Input arguments", while JAVA_TOOL_OPTIONS and
_JAVA_OPTIONS are read directly by the JVM, so don't show up in the
command line args
