Re: [Jython-dev] Problem with method overrides in latest CVS jython?

Hi Brian,

If I understand your test program correctly, it should work when I run it for 
PyTestA class, and fail for PyTestB. 

In my case it works for both, clone() is there.

What JDK version are you running? We've had some problems here before with 
Java not accessing protected methods properly. FWIW, I'm running JDK 1.3.1 
RC2 on Linux.

It is odd that you got a KeyError for my test program. I get a segfault 
(which may or may not be caused by a stack overflow). However, the same 
scenario in my real-world application definately causes an infinite 
recursion, I can see it in the stack trace. This is why I am suspecting a 
stack overflow for the test program as well.

Here's my output:

~/jython-2.1a1 > ./jython test.py
./jython: line 7:  8029 Segmentation fault      
/usr/local/jdk1.3.1/jre/bin/java -Dpython.home=/home/rseddon/jython-2.1a1 
-classpath "/home/rseddon/jython-2.1a1/jython.jar:$CLASSPATH" 
org.python.util.jython "$@"

If I add the "setSize" method into the intermediate class it runs properly.
