ResponseProcessor - AsyncHandlerActor crashed on tx HttpTx - java.nio.charset.CharacterCodingException: null

[Rob Gates]

I'm seeing the below a lot when running my tests having upgraded to 2.2.0. I didn't see these errors before upgrading.

The site in question doesn't appear to be the issue - I can't find any common link between the sites that cause the crash.

I can't seem to replicate it directly (eg with a single call to the site in the above example), but it seems to happen when running in parallel with other requests, and happens more often at higher requests/sec rates.

I believe this (or a related issue) is currently causing gatling to make far fewer requests than it should do - the requests/sec rates I'm seeing having upgraded are far lower.

Thanks,

Rob

Hi,

No offense, but if, like most users on this mailing list, you don't receive any notifications, you'd really benefit from subscribing properly, eg receiving a daily digest.

This issue has already been discussed here and dealt with.

I will sign up immediately!

I had searched the archives, and though I found a few related issues, hadn't found a solution - I wanted to raise it separately in case there was a separate issue. Could you please point me to the discussion that deals with it?

Thanks for all your hard work and a great product.

Cheers,

Rob

Thanks Stephane - problems (including the related performance issues) all resolved in the 2.2.1 snapshot!

Hi Stephane,

I encountered "java.nio.charset.CharacterCodingException: null" today and stumbled across this conversation. I was using 2.2.0 release but tried 2.2.1 snapshot as well. I see that the error occurs only for requests fetching PNG files but not JS files (I just checked these two). I've given below a simple reproducer which I tested and got the below error. Please try and let me know if you are able to reproduce. And if possible a quick fix too please :)

Update: Adding ".silent" in each of the request's exec suppresses this error and I'm going with it for now. Though adding silentResources in protocol won't help.  Also error happens for png, gif & woff file types so far but not JS or CSS. I also run this simulation through 2.2.1 & 2.3.0 snapshots and the issues mentioned before can be observed there too.

Hi,

This issue is actually already fixed, but not released yet: https://github.com/gatling/gatling/issues/3017

Thanks for reporting.

Not just binary, I'm seeing even CSS files response processors crashing.So, disabling TRACE level logging of request/response fixes all this? Awesome! Thank you.

Regards,

Mahesh

Do you have a reproducer showing crash on test files (such as JS or CSS)? You said you those were working fine in your previous email.

Sorry! Due to project deadline, I couldn't come up with a reproducer. But I'll get back to you soon on this.
