RFR [8039152] Need a way to suppress message when picking up JAVA_TOOL_OPTIONS

[Staffan Larsen]

My initial reaction is: Nooo! Please don’t add more options and special cases to the parsing of the command line and startup options.

My slightly more polished reaction is: can you provide a good use case where this is needed? The options and the message has been around for many years and not caused too much alarm.
