Frank Suchy created ISPN-5194: --------------------------------- Summary: HotRod client using protocolVersion "1.3" sends 2.0 0x29 code Key: ISPN-5194 URL: https://issues.jboss.org/browse/ISPN-5194 Project: Infinispan Issue Type: Bug Affects Versions: 7.0.3.Final Environment: Redhat Linux 2.6.18-400.1.1.el5 #1 SMP Sun Dec 14 06:01:17 EST 2014 x86_64 x86_64 x86_64 GNU/Linux Reporter: Frank Suchy Priority: Blocker While testing the 7.0.3 HotRod client, I ran into a cluster view issue (that's for another bug report) so I attempted to work around it by specifying protocol version 1.3 by calling configurationBuilder.protocolVersion("1.3") One of the operations used by the HotRod client is cache.isEmpty(). This call resulted in the HotRod client sending code 0x29 (41) to the server. The server rightly rejected it, so the client threw an exception. Below is a snippet from the HotRod client. Note that Codec13 is setting the operation code to 0x29.
