Cannot send partial message with

[OPeyrusse]

As we can see in the code snippet below, it is not possible to send TextMessage where isLast is set to false.

spring-framework/spring-websocket/src/main/java/org/springframework/web/socket/adapter/jetty/JettyWebSocketSession.java

Lines 218 to 220 in 43ff6d9

	protected void sendTextMessage(TextMessage message) throws IOException {
	useSession((session, callback) -> session.sendText(message.getPayload(), callback));
	}

spring-framework/spring-websocket/src/main/java/org/springframework/web/socket/TextMessage.java

Lines 62 to 65 in 43ff6d9

	public TextMessage(CharSequence payload, boolean isLast) {
	super(payload.toString(), isLast);
	this.bytes = null;
	}

However, the API exists in Jetty, in the form of Session#sendPartialText(String, boolean, Callable). Is there any reason for not using it?

https://github.com/jetty/jetty.project/blob/jetty-12.0.x/jetty-core/jetty-websocket/jetty-websocket-jetty-api/src/main/java/org/eclipse/jetty/websocket/api/Session.java#L99-L110

From basic testing, it seems that calling it is still not complying, but I may have made boggus changes and broken the code.

Thank you for any reply
