Punith DG updated OLINGO-999:
-----------------------------
Description:
I am not able to add more than one request to a batch ChangeSet as the
BatchManager has PipedOutputStream Writer which is causing infinite loop the
thread.
When I try to add a second request the thread enters to into infinite waiting
loop. Check the below sample code in which I'm trying to add requests.
ODataBatchRequest batchRequest =
client.getBatchRequestFactory().getBatchRequest("serviceURI");
BatchManager payloadManager = batchRequest.payloadManager();
ODataChangeset changeset = payloadManager.addChangeset();
ODataEntityCreateRequest<ClientEntity> createRequest =
client.getCUDRequestFactory().getEntityCreateRequest(new URI(serviceRoot),
entity);
createRequest.setFormat(ContentType.JSON);
changeset.addRequest(createRequest); // here the thread waits in infinite loop
due to piped streams sync problem.
The problem is observed in line "request.batch(req,
String.valueOf(contentId));" in addRequest() method of ODataChangesetImpl class.
It seems a known issue in Java -
