TODO

  • there is a known Bug in the methodID size in the Rust implementation I wonder how this ever worked^^
  • move JdwpHandler in its own repository and use it as a git submodule, to allow easier usage also for other repositories, for example jdb++
  • implement the --watchlist argument (not possible see issue)
