IIRC Jython's indirection causes the actual call in this case to originate
from the org.python.core package. Methods go through the proxy to act like
the real package/subclass, but fields do not. In other words, your
stringArray needs to be public, or you need to write an intermediate/shell
java class that exposes this field (e.g. a get method).
