    • Verified

      Tested OS/Browser:
                              XP-Home(sp2)/IE6
                              win 2000 pro(sp4)/IE6
                              win ME/IE5.5
                              (Firefox 1.0 should encounter the same problem)

      Tested build: j2re 1.6.0- build 30 (a regression since build 27)

      Problem:
      -------
      The map24 interaction applet app fails to load. The Java detection applet throws
      java.io.IOException: open HTTP connection failed exception.
      Priod to 1.6.0-b27, this applet works OK without any exception on the same test machines. It also works fine with MS VM.

      Steps to reproduce:
      ------------------
      1) Install j2re1.6.0-build 30 into the test system
      2) Go to http://www.map24.com/
      3) Click on "interactive" button at the right top corner.

      The Map24 app fails to load. The following exception is thrown (it fails at the Java Dectection applet) :
