Unexpected error occurred in scheduled task. java.lang.OutOfMemoryError: Java heap space

问题

I am using java websoket client to create a websocket connnect in java 8, this is my code:

import com.sportswin.soa.robot.common.SessionUtil;
import com.sportswin.soa.robot.model.entity.Robot;
import com.sportswin.soa.robot.model.enumn.RobotStatus;
import com.sportswin.soa.robot.service.impl.RobotService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

import java.net.InetAddress;
import java.net.URI;

/**

@Slf4j
@Component
public class WebsocketClientConnector {

    @Value("${com.dabai.robot.ws-url}")
    private String websocketUrl;

    @Autowired
    private RobotService robotService;

    public WebsocketClientEndpoint robotNewConnect(Long roomTypeId, String token, String userMark) {
        WebsocketClientEndpoint clientEndPoint = null;
        String websocketConnUrl = websocketUrl + "?token=" + token + "&roomTypeId=" + roomTypeId + "&robotFlag=1";
        try {
            String appMark = SessionUtil.getThreadLocal("appMark");
            clientEndPoint = new WebsocketClientEndpoint(new URI(websocketConnUrl));
            clientEndPoint.userSession.getUserProperties().put("userIdentity", userMark + "-" + appMark + "-" + roomTypeId);
            clientEndPoint.addMessageHandler(message -> {
                log.info("addMessageHandler:", message);
            });
        } catch (Exception e) {
            log.error("Websocket", e);
        }
        return clientEndPoint;
    }
}

recently this code throws Unexpected error occurred in scheduled task. java.lang.OutOfMemoryError: Java heap space makes me confusing. this is the full error stack output:
