Opens a class file. This method may be called just to examine whether the class file exists as well as to read the contents of the file.

This method can return null if the specified class file is not found. If null is returned, the next search path is examined. However, if an error happens, this method must throw an exception so that the search is terminated.

This method should not modify the contents of the class file. Use javassist.Translator for modification.
