OCPP 2.0.1 requires CSMS and Local Controllers to support RFC 7692 WebSocket compression, and recommends it for Charging Stations using mobile data connections. This feature was not implemented yet. Add the WEBSOCKET_COMPRESSION_SUPPORT boolean to JSONConfiguration, enabled by default for the server and disabled by default for the client. Bump the WebSocket library dependency from version 1.5.3 to 1.6.0, since the PerMessageDeflateExtension was broken in older versions.

Things to consider, java_websocket 1.6 has one breaking change, it no longer supports Java 1.7 https://github.com/TooTallNate/Java-WebSocket/releases/tag/v1.6.0 |

The Java-OCA-OCPP library source code does not support Java 1.7 either (use of lambdas, and build.gradle says sourceCompatibility = '1.8'), so I don't see any problem with that. |
