Class Overview
This is an abstract base class which is called by java.lang.ClassLoader
when ClassFormatError is thrown inside defineClass().
The purpose of this class is to allow applications (e.g. Java Plug-in)
to have a chance to transform the byte code from one form to another
if necessary.
One application of this class is used by Java Plug-in to transform
malformed JDK 1.1 class file into a well-formed Java 2 class file
on-the-fly, so JDK 1.1 applets with malformed class file in the
Internet may run in Java 2 after transformation.
