Major Description
The Stomp v1.1 spec defines that STOMP severs should no trim ws from message headers:
The STOMP 1.0 specification included many example frames with padding in the headers and many servers and clients were implemented to trim or pad header values. This causes problems if applications want to send headers that SHOULD not get trimmed. In STOMP 1.1, clients and servers MUST never trim or pad headers with spaces.
