Failed to start bean 'webSocketHandlerMapping'; nested exception is java.lang.IllegalStateException: Unable to initialize Jetty WebSocketServerFactory with latest spring and jetty vesions [SPR-14696]

Hi Team,

Earlier we were using

Spring websocket dependency:

---

<dependency>
     <groupId>org.springframework</groupId>
     <artifactId>spring-websocket</artifactId>
     <version>4.2.4.RELEASE</version>
</dependency>

JETTY dependency:

---

<jetty.version>9.2.1.v20140609</jetty.version>

And websocket configuration is as follows:

---

@Configuration
@EnableWebMvc
@EnableAspectJAutoProxy
@EnableWebSocket
public class WebMVCConfig extends WebMvcConfigurerAdapter implements WebSocketConfigurer {

private static final String NOTIFIER_ENDPOINT_URL = "/notificationHandler";

@Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
	registry.addHandler(socketHandler(), NOTIFIER_ENDPOINT_URL).setAllowedOrigins("*");
}

@Bean
public WebSocketHandler socketHandler() {
	return new NotificationSocketHandler();
}

@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
	configurer.enable();
}

@Bean
public DefaultHandshakeHandler handshakeHandler() {

	WebSocketPolicy policy = new WebSocketPolicy(WebSocketBehavior.SERVER);
	policy.setInputBufferSize(8192);
	policy.setIdleTimeout(600000);

	return new DefaultHandshakeHandler(new JettyRequestUpgradeStrategy(new WebSocketServerFactory(policy)));
}

This configuration was working fine..Later we found some native memory related(inflater/deflater issues) in old version of jetty..So we are going to upgrade the jetty version as well as the spring websocket version

But on just chaning the spring webscket version to 4.3.2
and <jetty.version>9.3.11.v20160721</jetty.version>..By changing the version the test cases which are passing earlier are failing with following stack trace

Stack Trace:

Is there any configuration that must be changed with this upgrade?

I could see the same stack in the following urls:

---

https://build.spring.io/browse/SPR-PERF-JOB1-524/

Search Tag: echoWebSocket

Request to please update if its a bug /configuration issue..

Thanks and Regards

Also this test case:

Our test case is similar to :

https://github.com/spring-projects/spring-framework/blob/master/spring-websocket/src/test/java/org/springframework/web/socket/client/jetty/JettyWebSocketClientTests.java

Request to please let me know if it works with latest jetty builds..

Venkata Satya Teja Siram commented

There are some test cases modified,but just wanted to know if this test case also need to be modified to support jetty9.3 version changes..

I found out that error could be on this line ContextHandler contextHandler = ContextHandler.getContextHandler(this.context);
Because we use @WebAppConfiguration we have MockServletContext that is not instance of ContextHandler.Context and method getCurrentContext return null

It seems you're not using the latest Spring Framework version; we've updated the websocket support in 4.3.5 to support changes in Jetty. See #19507.

Can you try with Spring Framework 4.3.5+ and report back here?

i use 4.3.7

Komdosh Indeed, this seems related to testing setup rather than pure Jetty support; could you create a minimal repro project so that we can reproduce the issue?

Yep, you could load it from here https://bitbucket.org/komdosh/minreproproject#clone

Did you succeed to check project?

Sorry for the late reply,

Could you reduce this projet to focus on the websocket part?
This contains a lot of unrelated dependencies and classes - including spring security configuration, overriding a lot of Spring configuration, and a dependency on Spring Boot (!!).
The following dependencies should be enough: org.eclipse.jetty.websocket:websocket-server, org.eclipse.jetty.websocket:websocket-api,
spring-webmvc, javax.servlet-api, spring-websocket, spring-messaging, jackson-databind and logging stuff.

I managed to trim down that sample, to start the server and connect a websocket client to the "http://localhost:8080/ex/chats/websocket" endpoint. You can check out the spring-framework-issues repository if you'd like to create a simple repro project.

Thanks!
