      When making a set with a document over 1 MB to Couchbase using the latest Java client to a Memcached-type bucket, an expected "Too Large" response is returned, but then the connection is dropped. The following application hangs on shutdown, and was compiled with the instructions at http://www.couchbase.com/communities/c-client-library. Other clients look to have similar behavior, so appears to be a server issue.

      import com.couchbase.client.CouchbaseClient;
      import java.net.URI;
      import java.util.Arrays;
      import java.util.List;
      import java.util.Date;
      import java.text.DateFormat;
      import java.text.SimpleDateFormat;
      import java.util.Calendar;

      public class App {

      public static void main(String[] args) throws Exception

      { List<URI> hosts = Arrays.asList( new URI("")); // Name of the Bucket to connect to String bucket = "TestBucket"; // Password of the bucket (empty) string if none String password = ""; CouchbaseClient client = new CouchbaseClient(hosts, bucket, password); int[] intArray = new int[1048576 * 2]; for (int i=0; i < (1048576 * 2); i++) intArray[i] = i; System.out.println("length is" + intArray.length); // Store a Document client.set("my-first-document", intArray).get(); // Retreive the Document and print it System.out.println(client.get("my-first-document")); // Shutting down properly client.shutdown(); System.exit(0); }
