/**
JThis is a dynamically loaded extension which extends This and adds
explicit support for AWT and JFC events, etc. This is a backwards
compatability measure for JDK 1.2. With 1.3+ there is a general
reflection proxy mechanism that allows the base This to implement
arbitrary interfaces.
The NameSpace getThis() method will produce instances of JThis if
the java version is prior to 1.3 and swing is available... (e.g. 1.2
or 1.1 + swing installed)
Users of 1.1 without swing will have minimal interface support (just run()).
Bsh doesn't run on 1.02 and below because there is no reflection!
Note: This module relies on features of Swing and will only compile
with JDK1.2 or JDK1.1 + the swing package. For other environments simply
do not compile this class.
