Issue222795

Calling the constructor of a PyObject subclass with arguments will
cause the __repr__() methods to be ignored. JimH hinted that this
would be solved in jpython1.1 (see below).

Your problem is that under the current JPython release, you can't
directly call the constructors of classes that subclass from PyObject
and get the expected result.  This is considered a clear design
mistake in JPython and will be fixed in 1.1.

This is actually a duplicate of bug 122790.
