public abstract class ClassQueryTool
extends java.lang.Object

The class-query tool loads classes using a classloader and calls "processClass" for each class encountered. This is highly expensive and sometimes dangerous excercise as the classloading may trigger static initializers and may exhaust the "permgen" space of the Virtual machine. If possible anyhow, do not use this class.
