    Alpha 6 - EJB3StandaloneBootstrap.scanClassPath - very slow

    Vilmundur Pálmason Newbie

      Hi, I am having problems with embedded EJB3:

      In my case, I am running from within eclipse, the launch configuration has
      a *lot* of class directories and jars.

      EJBStandaloneBootstrap.boot(null) takes 2 seconds.

      EJBStandaloneBootstrap.scanClassPath() takes 8 minutes on 100%cpu
      (1.9Ghz Pentium M).

      When I sample the stack, most of the time seems to be spent looking for
      "int.class" (sometimes int[].class) in every class directory - over and over again.

      There is definitely some room for improvement there.

      A typical stack trace follows:

      File.exists() line: not available [local variables unavailable]
