Back when JavaHelp was used, it was a runtime dependency, and jtreg looked for the jar file when it started up, just in case it was required.
The "bad practice" was that we didn't have a good single top-level target or variable to define the dependencies required to execute jtreg, so we ended up with cut-n-paste collections of dependencies in all these test, that we are now finally eliminating.
