Issue1114375

I installed jython using apt-get install jython
I am running JDK1.5, and do not have the debian java
package installed.

I executed "jython" and it complained that
/usr/bin/java didn't exist, so I executed "ln -s
/usr/java/jdk1.5.0/bin/java from my /usr/bin directory.

I then executed "jython" and got the following :

I tried again, in case it was related somehow to
loading the new classes and got :

If you try this on < JDK1.5 do you get the same behaviour?  Currently 
Jython does not entirely support JDK1.5.

I noticed the same error when setting up readline support.
It so happens that if the registry file has  

  python.console=org.util.ReadlineConsole 

but python.console.readlinelib is commented out, then
exactly this error is raised (its defaulted to EditLine in
org.python.util.ReadlineConsole). In my case adding

  python.console.readlinelib=GnuReadline

and properly setting up libreadline-java fixes the problem. 

So i think this report was likely a configuration error on
the users part or perhaps in the debian jython package.

Most likely user error or jdk 5 problems -- closing.
