assertRaises contextManager behaves differently in python 2.6

[GoogleCodeExporter]

What steps will reproduce the problem?

The following test (for the JPype1 project  @ 
https://github.com/originell/jpype) works on python 2.7 and python 3 but fails 
in python 2.6:
        with self.assertRaises(JavaException) as cm:
            self.jpype.exc.ExceptionTest.throwRuntime()
        self.assertIs(cm.exception.javaClass(), java.lang.RuntimeException)

What is the expected output? What do you see instead?
I'm expecting it to work.

Traceback (most recent call last):

File "/home/travis/build/baztian/jpype/test/jpypetest/exc.py", line 31, in 
testExceptionThrown

self.assertIs(cm.exception.javaClass(), java.lang.RuntimeException)

AttributeError: 'tuple' object has no attribute 'javaClass'



What version of the product are you using? On what operating system?
0.8.0
