What steps will reproduce the problem?
1. run "~/jython2.7rc2/bin/jython console.py"

What is the expected output? What do you see instead?

expected: console window should pop up

actual: no error, and instead a Traceback:

 Traceback (most recent call last):
   File "console.py", line 36, in <module>
     class Console:
   File "console.py", line 37, in Console
     PROMPT = sys.ps1
 AttributeError: '<reflected field public org.python.core.PyObject o' object has no attribute 'ps1'

What version of the product are you using? On what operating system?

jythonconsole: Subversion head
Java: Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.8.0_45
Jython: 2.7rc2

This worked in Jython 2.7rc1.

It looks like we have changed how the REPL is set up in Jython compared to what it was in the past, so it's more compliant with CPython. In particular the demo code used a behavior that is specifically ruled out in the Python docs (and causes problems in tools expect a standard Python): https://docs.python.org/2/library/sys.html#sys.ps1
