Using of AdditionalBound in cast expressions

This can be compiled:

Object x = (Number&Serializable)~0;

This also can be compiled:

void method()
{
    method2((Number&Serializable)~0);
}

<T extends Number&Serializable> void method2(T x)
{

}

An example where the cast is actually needed:

void method(Object o)
{
  method2((List&AutoCloseable)o);
}

<T extends List&AutoCloseable> void method2(T v)
{

}
