Grails 3.2.4 grails-spring-websocket 2.3 Error - spring

Question

=== UPDATE === (see original post below)
Though the bug fix initiated by zyro brought some improvements, there error is still not disappeared completely. It still looks like this:

So actually only the second part of the error disappeared...
=== ORIGINAL POST ===
I find a lot off following erros in my Tomcat 8.0.28 catalina.out logs. I guess it is caused by the websocket plugin, which I used. I did the implementation in a service class like following:
def publishNewChart(def productId) {
def linechart = chartService.getLinechart(Product.load(productId));
brokerMessagingTemplate.convertAndSend("/topic/trade_chart/" + productId, linechart);
}
And on the client side following:
$(function() {
var socket = new SockJS("${createLink(uri: '/stomp')}");
var client = Stomp.over(socket);
client.connect({}, function() {
client.subscribe("/topic/trade_chart/${product?.id}", function(message) {
var messageJson = $.parseJSON(message.body);
refreshPriceChart($.parseJSON(messageJson.data));
brushed();
});
});
});
Does anybody have a clue, where the errors come from and how to deal with them?
Thanks a log in advance!
