jtreg support for --patch-module?

[Roger Riggs]

Hi,

For a test, I need to patch a class in a module.
I'm stumped on the correct series of @library, @build and @run setup to 
see it automatically
pass the --patch-module options to javac and java.

Am I expecting too much and have to revert to explicitly spawning the 
compile and run steps?

Thanks, Roger
