Message882

Sometimes when creating an Instance of a class the
following Exception will happen:

java.lang.NullPointerException

        at
org.python.core.PyJavaClass.setConstructors(PyJavaClass.java)
        at
org.python.core.PyJavaClass.initConstructors(PyJavaClass.java)
        at
org.python.core.PyJavaClass.__call__(PyJavaClass.java)
        at org.python.core.PyObject.__call__(PyObject.java)

Jython appears to have trouble creating an instance of
classes that were dynamically added.


WORKAROUND...

To avoid this problem, put the class in Java's
Classpath before starting Jython.
