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

[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.
