Class ExceptionSet

public class ExceptionSet extends Object implements Serializable

Class for keeping track of exceptions that can be thrown by an instruction. We distinguish explicit and implicit exceptions. Explicit exceptions are explicitly declared, thrown, or caught. Implicit exceptions are runtime faults (NPE, array out of bounds) not explicitly handled by the user code.
