This task will add a test case for JShell crashing by running the following example code. This bug has been fixed by https://bugs.openjdk.org/browse/JDK-8292755

// Case A
@FunctionalInterface
interface RunnableWithThrowable {
    void run() throws Throwable;

    // You can also replace `static` with `default` and test again
    static RunnableWithThrowable getInstance() {
        return () -> { throw new NotExist(); };
    }
}

// Case B
@FunctionalInterface
interface RunnableWithGenericException<X extends Throwable> {
    void run() throws X;

    static RunnableWithGenericException<?> getInstance() {
        return () -> { throw new NotExist(); };
    }
}
