RFR: 8280642: IllegalAccessError thrown by ObjectInputStream.resolveProxyClass is not handled [v2]

[Roger Riggs]

> During deserialization of a serialized data stream that contains a proxy descriptor with non-public interfaces
> `java.io.ObjectInputStream` checks that the interfaces can be loaded from a single classloader in `ObjectInputStream.resolveProxyClass`.
> If the interfaces cannot be loaded from a single classloader, an `IllegalAccessError` is thrown.
> When `ObjectInputStream.readObject` encounters this case, it reflects an incompatibility
> between the classloaders of the source of the serialized stream and the classloader being used for deserialization.
> When a proxy object cannot be created from the interfaces, `ObjectInputStream.readObject` should catch
> the `InvalidAccessError` and throw `InvalidObjectException` with the `InvalidAccessError` as the cause.
> This allows the application to handle the exception consistently with other errors during deserialization.
