Hi,
I'm using websockets with embedded jetty and somehow the websocket related
objects are not cleaned up even after closing the connection. I'm using it
as follows:
@ServerEndpoint(value="/websocket/")
public class WebSocketEndpoint {
@OnOpen
void foo() {}
@OnClose
void bar() {}
}
etc. Everything is working fine, except that the endpoint objects are not
getting gc'd. Looks like it is referred by ApplicationShutdownHooks or
something. Following is a partial snapshot of referred objects:
this - value: WebSocketEndpoint #1
<- websocket - class:
org.eclipse.jetty.websocket.jsr356.endpoints.JsrAnnotatedEventDriver,
value: com.oracle.ofsc.chat.endpoints.WebSocketEndpoint #1
<- incomingHandler - class:
org.eclipse.jetty.websocket.jsr356.JsrSession, value:
org.eclipse.jetty.websocket.jsr356.endpoints.JsrAnnotatedEventDriver #1
<- _bean - class:
org.eclipse.jetty.util.component.ContainerLifeCycle$Bean, value:
org.eclipse.jetty.websocket.jsr356.JsrSession #1
<- [2] - class: java.lang.Object[], value:
org.eclipse.jetty.util.component.ContainerLifeCycle$Bean #82
<- array - class: java.util.concurrent.CopyOnWriteArrayList,
value: java.lang.Object[] #2869
<- _beans - class:
org.eclipse.jetty.websocket.server.WebSocketServerFactory, value:
java.util.concurrent.CopyOnWriteArrayList #70
<- webSocketServerFactory - class:
org.eclipse.jetty.websocket.jsr356.server.ServerContainer, value:
org.eclipse.jetty.websocket.server.WebSocketServerFactory #1
<- [0] - class: java.lang.Object[], value:
org.eclipse.jetty.websocket.jsr356.server.ServerContainer #1
<- array - class: java.util.concurrent.CopyOnWriteArrayList,
value: java.lang.Object[] #2001
<- _lifeCycles - class:
org.eclipse.jetty.util.thread.ShutdownThread, value:
java.util.concurrent.CopyOnWriteArrayList #55
<- [36] - class: java.lang.Object[], value:
org.eclipse.jetty.util.thread.ShutdownThread #1
<- table - class: java.util.IdentityHashMap, value:
java.lang.Object[] #1084
<- hooks (sticky class) - class:
java.lang.ApplicationShutdownHooks, value: java.util.IdentityHashMap #1
Any help is greatly appreciated. I'm trying to debug further.
Thanks,
amit
