Category: DynamicJava Group: 3: Ugly Status: Open Resolution: None Priority: 3 Private: No Submitted By: Dan Smith (dlsmith) Assigned to: Dan Smith (dlsmith) Summary: Crash when creating a class in an illegal package Initial Comment: DynamicJava allows classes to be created in arbitrary packages, but doesn't cleanly handle errors when adding to a package is not allowed. Example: > package misc; > class Foo {} > Foo.class class misc.Foo > package java.lang; > class Mom {} > Mom.class [error occurs] Stack trace: edu.rice.cs.util.UnexpectedException:
