The PythonActor uses Jython and not all of Python is supported by the version of Jython that ships with BCVTB and Ptolemy II. It looks like it is fairly old:
bash-3.2$ svn log $PTII/lib/jython.jar

Updated to Jython 2.5.4-rc1
Jython 2.7.0 is supposed to support all of what is in the C version of Python 2.7.
The Jython 2.7.0 jar file is 37Mb, which is an increase from the Jython 2.5.4-rc1 size of 10Mb. I replaced $PTII/lib/jython.jar with the 2.7.0 jar file and the tests passed
wget -O jython.jar http://search.maven.org/remotecontent?filepath=org/python/jython-standalone/2.7.0/jython-standalone-2.7.0.jar
mv jython.jar $PTII/lib/jython.jar
cd $PTII/ptolemy/actor/lib/python/test/
make
Perhaps try updating your copy of jython.jar and then see if the with statement works.
I committed an updated version of jython.jar to the ptII tree, so I'll see what breaks in the tests over the next few days.
