> java.util.Collections$UnmodifiableRandomAccessList is not compatible with Eclipse Milo built-in types.
> When writing to the OPC-UA driver a simple array of Double, I receive the following error:
> [org.eclipse.milo.opcua.stack.core.serialization.OpcUaBinaryStreamEncoder:608]: Not a built-in type: class java.util.Collections$UnmodifiableRandomAccessList
> When writing a single value in the array the type is PlcDouble instead of PlcList, and there is no error.
>  
> I think that a possible solution could be changing the underlying type, or better to change the getter for the value.

> I will try to find myself a solution and I will keep you posted.
