One of the patches to proceed this one is an entry point that javac can use to pick up the runtime options. There is also a recent javac change to pick up options from an environment variable in a similar (but not identical) way to _JAVA_OPTIONS. Once all the pieces are in then I think the command line option story will be much better.

It’s an open issue:

The JBS issue about the CLI option consistency and related to GNU-style
   https://bugs.openjdk.java.net/browse/JDK-8152218

There are multiple ways to take argfiles that should also be examined:
