 * @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 when another exception is raised in a catch clause,
 * the finally clause of the same try statement is still executed, other catch clauses
 * of that try statement aren't, and control is transferred to the nearest enclosing
 * exception handler afterwards.
