The only code that constructs a `CLHSDB` object, and therefore triggers the potential call to `doUsage()`, is `CLHSDB.main()`, and it is only called from `SALauncher` when using `jhsdb clhsdb`. We could get rid of `main()` and have some other entrypoint that is passed the values of all the possible options, rather than having to parse them in CLHSDB.java.

I think `debugd` and `jinfo` are also remove `main()` if they have because they do not provide commands like `jstack`.
I will file it to JBS, and will fix them later.
