This issue is solved as of SAP Cloud SDK version 3.11.0.
Using java SAP Cloud SDK version 3.9.0
We have a code snippet for reading Outbound Delivery Items from S/4 while looks like this:
List<OutbDeliveryItem> items = new DefaultOutboundDeliveryV2Service()
.getAllOutbDeliveryItem()
.filter(OutbDeliveryItem.DELIVERY_DOCUMENT.eq("someDocument"))
.execute(someDestination);
The code executes successfully and is able to read the items from S/4. But below exception always gets logged:
ERROR com.sap.cloud.sdk.odatav2.connectivity.cache.metadata.GuavaMetadataCache - Error occurred while populating metadata:
com.sap.cloud.sdk.datamodel.odata.helper.ODataVdmErrorResultHandler$ErpODataException: The endpoint responded with HTTP error code 401.
Logon failed. 401 Not authorized.

I examined our destination setup on Cloud Foundry and the setup on cloud connector as well. The setup is correct. If it was a problem with the setup, then the code would not have been able to read the items from S/4.
Upon debugging the sdk code a bit, I found a method com.sap.cloud.sdk.odatav2.connectivity.OdataQuery.execute() while tries to execute the read request 2 times. First time the read fails as the code is not able to fetch metadata and throws the exception that I've mentioned earlier in my question. Second time the read is successful (Code is able to read the metadata). I could have pasted the code snippet from sdk here but I am not sure if it is appropriate to do so.
I have following questions:
Please let me know if you require any more info.
P.S.: I have seen a lot of comments on this blog from people facing the same problem.
This issue is solved as of SAP Cloud SDK version 3.11.0.
