  Uh… PermGen? What year is it? This must be blog spam from the past.

  Detecting? It's safe to assume that if there's any statics there's a permgen leak.

  And this is why I avoid all Java apps I can -- there is always a need for some memory tuning. C++, Lisp, Perl, Go, Python, even Javascript can all use all the memory in my computer have without any action on my part, only Java keeps having the problems with it.
