Server Sent Events not working in Chrome

i am developing a web application with angular 4 and java. I am using server sent events to send some text data to the frontend. In the backend i am using jersey and this is my backend code

eventOutput.write(new OutboundEvent.Builder()
       .id(decodedToken)
       .name("responseBody")
       .data(String.class, respBody.toString()).build());

Frontend i am using angular 4 and the code looks like

var evtSource = new EventSource("url");
 source.addEventListener('eventName', (event) => {
    console.log(event);
});

Everything works fine in Mozilla firefox. When i use chrome with tomcat and windows everything works fine. But with tomcat+linux and chrome, i see the error in the console.as

EventSource's response has a charset ("iso-8859-1") that is not UTF-8. Aborting the connection.

What could be the issue. What is the fix? Please help. Any help would be appreciated. Thanks.

If the issue is with tomcat in linux, you can update bin\startup.sh the following line

export JAVA_OPTS="-Dfile.encoding=utf-8"

See Force tomcat to use UTF-8 in linux tutorial

Tomcat supports charset : iso-8859-1 by default. Please try

@Produces("application/json;charset=UTF-8")
eventOutput.write(new OutboundEvent.Builder()
       .id(decodedToken)
       .name("responseBody")
       .data(String.class, respBody.toString()).build());
