After some testing, we are happy to release  brasilwin_1_2, which features Java Jython 2.5alpha3 support!

To try Jython support:

  • download brasil 1.2 and install Jython 2.5 alpha 3.
  • Download and install Java JDK 1.5 or higher. We have done our test with Jdk 1.6
  • But be sure to have at least 1Gb of RAM, adding -Xms1024m   -Xmx1024m  to the launch line of jython.bat and then try something like: C:\\jython2.5a3\\jython.bat brasilWin.py
Because Jython is still in alpha stage, report every bugs leaving a comment below. For production use is still higly suggested to stick with python 2.5

Other Notes:

  • At the time of writing, Jython version uses about 230MB of RAM to work properly. The memory seems to grow, and this is a bit strange.
  • Because Jython interpreter is still in alpha stage, overall performance are sub optimal, so avoid to compare it. In detail, please ignore MB/Sec.
  • Standard output does not behave like the python 2.5 version, anyway the script works fine.
  • Performance on JDK 1.6 At the time of writing jython seems about 40% slower, which is a good result considering all the zipping logic is written in python.
