We use the jenkins-cli.jar to attach new slaves and this has been working successfully in v1.534, however when upgrading to v1.554.1, we are unable to do so and a "SEVERE: I/O error in channel Chunked connection" error occurs.
Tested on linux slaves using java version "1.6.0_35" and "1.7.0_45" and the same error occurs.
Attached console output to error.log
Workaround: -Dhudson.diyChunking=false on both slave/agent and master sides
