Basic stuff doesn't work

[sumlin]

There is a diff with a testing code: https://pastebin.com/1Xmm8dTj

For JSON please set isJson = true in both client and server runners.
For SOAP isJson = false.

JSON: can't connect to the server, have an error:
10:43:07.753 [Thread-2] DEBUG eu.chargetime.ocpp.WebSocketTransmitter - WebSocketClient.onClose: code = 1002, message = Invalid status code received: 404 Status line: HTTP/1.1 404 WebSocket Upgrade Failure, host closed = false

SOAP: message parser can't parse documents, it produces a null value in Communicator.java:238.

https://github.com/ChargeTimeEU/Java-OCA-OCPP/tree/revert-33-master helps with connection, but when I send boot and then auth requests, client gets null as a boot response and nothing as a auth response.

My mistake, JSON works pretty fine, but the problem with SOAP is still there
