public final class ExceptionTable extends Attribute
This class represents the table of exceptions that are thrown by a
method. This attribute may be used once per method. The name of
this class is ExceptionTable for historical reasons; The
Java Virtual Machine Specification, Second Edition defines this
attribute using the name Exceptions (which is inconsistent
with the other classes).
