// In this test, method main() in class CheckedExceptions declares that it
// throws I, where I is an interface.  This should not cause an assert nor an
// exception because JVMS 4.7.5 says that type checks of the classes listed
// in the Exceptions attributes are only enforced at compile time.  (Note that
// the types in a method's throws clause are passed to the JVM using the
// Exceptions attribute.)
