`JAVA_OPTS` or `JVM_ARGS` would be fine, though I'm still okay with
`JAVA_ARGS` since technically they are arguments to java itself. I used
`JAVA_ARGS` because that's what the .bat scripts were using, and I was trying
to establish parity between the .sh and .bat scripts. If everything else looks
good to you, you can make the change before committing, or I can push an update
to the PR.---
