/**
 * @assertion If an exception is raised during execution of an on-catch clause, this will transfer
 * control to the handler for the finally clause, causing the finally clause to execute
 * in this case as well.
 *   If no exception was raised, the finally clause is also executed. Execution of the
 * finally clause could also raise an exception, which will cause transfer of control to
 * the next enclosing handler.
 * @description Checks that a throw statement inside a finally clause replaces the current exception
 * and unwinds the call stack from the new location.
