23 * This unchecked exception is thrown by the host VM. It captures all errors
24 * and exceptions that can occur at the load of a JPF class, which includes
25 * defining, and resolving it. Here are some of the scenarios that this
26 * exception is thrown and captures the corresponding exception:
27 *
28 * * if the representation does not represent a class with the requested
29 * name, loading throws an instance of NoClassDefFoundError
30 *
31 * * if any of the superclasses of a class, is the class itself, or if
32 * any of the superinterfaces of an interface, is the interface itself,
33 * loading throws an instance of ClassCircularityError
34 *
35 * * if the representation is not a ClassFile structure, loading throws an
36 * instance of ClassFormatError
37 *
38 * If this exception is thrown during the initialization of VM, and the failed
39 * class is a system class, or creating of the main thread in not successful, we
40 * immediately bail out by throwing JPFException.
41 *
42 * While JPF is running, this error is handled by throwing an exception at the
43 * SUT level. This exception is handled if it is thrown by
44 *
45 * 1. a native peer method,
46 * 2. Intruction.execute(),
47 * 3. ThreadInfo.creatAndThrowException()
48 * 4. VM.initialize() // here it is handled only if it a non-system class
49 *
50 * If this exception is thrown by a Listener, the host VM throws JPFListenerException.
