Hi, Jython-users,

I am trying the Jython 2.7 beta 1 standalone downloaded from:


but found some issues running it on Windows 8 platform. The same commands works fine on Linux. Not sure if it's an known issue or not.

Below are the test results on Linux and Windows w/o the workaround of adding "-Dpython.concole=org.python.util.InteractiveConsole".

The stack trace is also attached.

The non working basic command like aa="aa" makes Jython 2.7 beta 1 not usable on Windows.

Is there any workaround or is there a plan to fix it soon?

Thanks a lot for your help.



jython 2.7 beta 1 standalone:


1. aa="aa" works.
2. sys.stdin.readline() works.
3. CTRL +C works.


1. aa="aa" hangs. CTRL + D  + enter to exit
2. sys.stdin.readline() hangs. CTRL + D or CTRL + C not working. need to kill the java process
3. CTRL + C shows a heart. Hit "enter" to exit with this message:
LookupError: unknown encoding 'ms936'

jython 2.7 beta 1 standalone + -Dpython.console=org.python.util.InteractiveConsole:


1. aa="aa" works
2. sys.stdin.readline() works.
3. CTRL + C works.


1. aa="aa" hangs. CTRL + D  + enter to exit
2. sys.stdin.readline() works.
3. CTRL + C works.


The stack trace when aa="aa" hangs looks like this:
