Comment #3 on issue 659 by pekka.klarck: Jython 2.5.2 (beta 2) compatibility http://code.google.com/p/robotframework/issues/detail?id=659
A bad news is that Jython 2.5.2 beta 2 is quite a bit slower to start on Windows than 2.5.1. On Linux the start-up time has, on the other hand, improved slightly. For more information about this and Jython start-up time problems in general see http://bugs.jython.org/issue1380.
