Systematic "RSV n" errors with stochastic "n"s

[ComradeWoland]

Hello, comrades!
There are errors "RSV n" with stochastic "n"s detected.
The WebSocket server is a small chat engine, available via wss: connection. It works with some stable periods, intermediated with periods of "RSV n" errors sent to stderr.

WTF may be this?

Hey @ComradeWoland,
what client are you using?

Could it be that you are using a .NET client?

Greetings
marci4

[ComradeWoland]

No, man, this bug appears while Google Chrome (latest version) connects to my WSS server.
My app uses WSS to support WebRTC connection establishing and text messaging inside Video chat roulette, but connection sometimes unstable, and server log is full of bugs.

[marci4]

Hey @ComradeWoland,

could you please activate the debug output with WebSocketImpl.DEBUG = true;

I cannot reproduce this problem with my private project right now (nether wss nor ws)
Maybe you could also try rebuild the jar directly from the sources here on github (I merged some pull requests, but was not able to update maven/gradle yet)

Also I just got the idea that you maybe wanna use Draft17 and not Draft10 for your project (Read up on the drafts here), because as documented it implements Hybi 17/RFC 6455 and is currently supported by Chrome16+ and IE10.

Greetings

[micamo2k17]

Hi,

same error here. In my case it's always "bad rsv 3", seems to appear at random moments, but quite often. Didn't have this problem when using WS instead of WSS.

Thank you for any indication.

[marci4]

Hello @micamo2k17,

could you please activate the debug output with WebSocketImpl.DEBUG = true; before you start the websocket server
and then post the log here please.

When does this problem occur?

• Which Draft are you using? (I really hope Draft_17 :) )
• Do you ping the websocket server?
• Do you send a lot of messages or no messages?
• Do you use any other extension which might interfere with the websocket connection?
• Are you using any specific sub-protocol?

Right now I don't have any problems using a wss in production.

Greetings
marci4

[micamo2k17]

Hi @marci4

I activated debug mode. The following are two cases of that error (one with debug off, one on). As you can see, the number following "bad rsv" actually changes also in my case:

Without WebSocketImpl.DEBUG = true;

E/SERVICE: WebSocket did fail with error: org.java_websocket.exceptions.InvalidFrameException: bad rsv 1
D/WSServer: onError: org.java_websocket.exceptions.InvalidFrameException: bad rsv 1
W/SERVICE: WebSocket closed

With WebSocketImpl.DEBUG = true;

E/SERVICE: WebSocket did fail with error: org.java_websocket.exceptions.InvalidFrameException: bad rsv 4
D/WSServer: onError: org.java_websocket.exceptions.InvalidFrameException: bad rsv 4
I/System.out: send frame: Framedata{ optcode:CLOSING, fin:true, payloadlength:11, payload:[3, -17, -65, -67, 98, 97, 100, 32, 114, 115, 118, 32, 52]}code: 1002
I/System.out: write(13): {����bad rsv 4}
W/SERVICE: WebSocket closed

Trying to answer to your questions:

• Which Draft are you using? (I really hope Draft_17 :) )
  How can I know that? Right now my dependency is 'org.java-websocket:Java-WebSocket:1.3.0'
• Do you ping the websocket server?
  Yes, I can ping the device where the web socket server is. I also can telnet the websocket server's port, both before the error, and after.
• Do you send a lot of messages or no messages?
  There are moments in which no messages are exchanged. In other moments, a lot of messages are exchanged very quickly. The error seems to happen when a lot of messages are exchanged in no-time.
• Do you use any other extension which might interfere with the websocket connection?
  My scenario involves a webview, on the same app that hosts the web socket, which connects to it. Nothing more.
• Are you using any specific sub-protocol?
  The problem only happens when using WSS. No problems with non-secure WS.

Thanks for your help!

[marci4]

Hello @micamo2k17

first of all it looks like you are using an outdated version of the lib (Check the readme for the latest version)

Maybe this fixes your issue already.

If not please also include the debug print out when the connection is opened :)

Greetings
marci4

[micamo2k17]

Hi @marci4

I couldn't find a readme for a newest version of the lib. Tried 1.3.1 (I saw it from the available branches/tags list) but the dependency could not be resolved.
However, when the connection is opened, the following is logged:
I/System.out: open using draft: Draft_17
So I believe we're using the updated build.

Thanks

[marci4]

Hello @micamo2k17,

that is not an indication that you are using the latest build. It looks like you are actually using a outdated version.

How do you build your project? What do you use? Maven, Gradle?

Greetings
marci4

[micamo2k17]

Hi @marci4

I'm using gradle. How can I select a new version?

Thank you!

[marci4]

Hello @micamo2k17

please add a custom maven repository to your repositories list
maven { url "http://clojars.org/repo" }

The result may look like this

repositories { mavenCentral() maven { url "http://clojars.org/repo" } }

For compiling just add compile "org.java-websocket:java-websocket:1.3.2" so you are using the latest version.

Greetings
marci4

[micamo2k17]

Hi @marci4

Just tried that, doesn't seem to resolve the dependency either: Error:Failed to resolve: org.java-websocket:java-websocket:1.3.2

Regards,
micamo1k2017

[marci4]

Hello @micamo2k17
could you maybe join the IRC Server here http://webchat.freenode.net/?channels=java-websocket

I quess it will be easier for both of us to fix this :)

Greetings
