Issue1088

(On Windows)

If I run test_third.py (below) with Jython2.5a, it runs fine. However,
if beforehand I run the script with Jython 2.2, it will subsequently
fail with Jython2.5a as follows:
>"D:\Tools\jython2.5a1+\jython.bat" test_third.py
0
Traceback (most recent call last):
  File "test_third.py", line 6, in <module>
    print instance.total
AttributeError: 'Example' object has no attribute 'total'

=========

test_third.py is:
"""
import myClass

instance = myClass.Example()
print instance.total
instance.inctotal()
print instance.tota
"""
where myClass.py is the attached file

Error copying + pasting test_third.py:
"""
import myClass

instance = myClass.Example()
print instance.total
instance.inctotal()
print instance.total
"""

This is fixed as of r4999. The problem was the new compiler wasn't 
comparing the MAGIC of the bytecode, so it was using the old, incompatible 
bytecode
