1. The driver tried to `arraycopy()` a `Long`, which caused `ArrayStoreException`.
2. GUIDs are structured objects, that matters when it comes to byte ordering.
The OPC-UA protocol uses little (mixed) endian GUID encoding format, while Java
uses the standard big endian one (RFC4122), so conversion is needed.
