The package statement does not ensure that access occurs from this class.
Creating 'dynamicism' means using indirection. Jython's indirection
means that the attribute request may not originate in the class found
in the generated .java file.

Yes. You can set python.respectJavaAccessibility to false and use Jython.
Even if you do not do so, you do not have to abandon Jython. Instead,
write only a wrapper class in java that makes access
Jython-friendly, then go about the project in Jython.
