Can't execute org.apache.chemistry.opencmis.client.api.Session.query()  method under WL 10.x app server because HTTP POST chunking value is set to > 64k in size
----------------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: CMIS-416
                 URL: https://issues.apache.org/jira/browse/CMIS-416
             Project: Chemistry
          Issue Type: Bug
          Components: opencmis-client-bindings
    Affects Versions: OpenCMIS 0.4.0
         Environment: WebLogic 10.3 running under Windows Server 2008
            Reporter: George Florentine
             Fix For: OpenCMIS 0.5.0


On WebLogic 10.3, the HTTP chunking size for keep-alive sessions must be < 64k size or an HTTP POST command will fail. In the 0.4.0 version of HttpUtils the BUFFER_SIZE constant is set to a pretty large value (2 * 1024 * 1024 bytes), set on line 54 of HttpsUtils.java . With this setting, HTTP POST methods that go through the HttpUtils.invoke() method fail with an error on WL 10.3.x servers. On line xxx, this statement:

conn.setChunkedStreamingMode(BUFFER_SIZE);

sets the buffer size and the subsequent write of the buffer fails. Reducing the  size of BUFFER_SIZE to < 64k solves this issue.
