### What happened?
If I attempt to access an OPC-UA node by GUID, I'm getting the following
exception:
```
Exception in thread "main" java.lang.ArrayStoreException: arraycopy: source
type java.lang.Long is not an array

```
Example code to reproduce the issue:
```
PlcDriverManager driverManager = new PlcDriverManager();
try (PlcConnection opcuaConnection =
driverManager.getConnection("opcua:tcp://opcuaserver.com:48010")) {
PlcReadRequest request = opcuaConnection.readRequestBuilder()
.addItem(
"VariableWithGuidNodeId",
"ns=2;g=5CE9DBCE-5D79-434C-9AC3-1CFBA9A6E92C"
)
.build();
PlcReadResponse response = request.execute().get();
System.out.println(response.getObject("VariableWithGuidNodeId"));
}
```
It applies to the latest revision of `develop` branch too.
I have already posted a PR to fix it:
