This version adds several conveniences to make using Java from Python more seamless:

• The Java class hierarchy is now reflected in Python, so isinstance and issubclass now work correctly with Java classes and objects.
• Java exceptions are now represented as objects of their actual type rather than a generic JavaException class. In conjunction with the previous point, this means that standard Python try ... except syntax can now be used to catch Java exceptions.
• Python “unbound method” syntax is now supported for Java objects, e.g. ClassName.method(instance, args).
