Untraceable fatal Exception caused by java.lang.IllegalArgumentException: byteString == null

[marcusmotill]

Originally in Retrofit issues, Jake told me to post this here:

From time to time I am experiencing this fatal error when performing a request. It only happens to one request at a time and I cannot get it to go away until I uninstall and reinstall the application. I am using:
com.squareup.retrofit2:retrofit:2.0.0-beta3

and here is the error:

E/AndroidRuntime: FATAL EXCEPTION: OkHttp Dispatcher

Let me know if you need more information

EDIT: I was able to get the error to stop if I went to system setting and cleared the app cache manually

Somehow your cache is being corrupted. Are you able to reproduce?

[marcusmotill]

Unable to reproduce. Seems to happen randomly

No clear action for us to take here. If you can figure out how to reproduce this, please let us know.

[marcusmotill]

Sounds good. Thanks for looking into it

It has been also reported here: hub4j/github-api#265 (effectively, from one of Jenkins plugins).

CC @ligi . Maybe he could provide reproduction steps

[KostyaSha]

Reproduced, have test case ;)

[niqo01]

Not reproducible for me just to add it's happening on Motorola Marshmallow for me: http://crashes.to/s/e86f7ac4202

I have started seeing a similar crash in my app in the field, being reported by Firebase. Since I don't have a device with the problem in front of me I can't get a lot more information. I am using retrofit:2.7.0,

But the stack trace is similar:

@martin-academia which version of OkHttp are you using? The error suggests a corrupted cache entry, so either we try to work out root cause (code, or external factors) or improve error handling for this case.

bytes.write(ByteString.decodeBase64(line));

Ideally we would need a reproduction with 4.9.0 or 3.12.12? I know that might be hard if you can't repro yourself.

[martin-academia]

Oh interesting, we didn't have an explicit dependency on OkHttp in our build.gradle, so I assume we were getting some default from retrofit 2.7.0.
I just tried moving to 4.9.0 and ran into compile problems, so until I can migrate I'm going to stay in version 3. As far as I can tell the latest 3.x.x is 3.14.0, so I'm explicitly including that. I'll let you know if we get more repros with that version.

[martin-academia]

One thing I noticed: When we were constructing the OkHttpClient, we created the cache with context.cacheDir as the directory. I didn't realize until I just looked at it that it's putting its cache files directly in that directory. Our app may be putting other stuff in that directory as well, so there is the potential for a collision.
I'm not sure whether that's the problem or not, but it seems unsafe so I'm going to change my app to put the OkHttp cache in some subdirectory of context.cacheDir.

[yschimke]

That's a great data point. 3.14 isn't maintained. So we would fix a bug on 4.x (Kotlin and Android 5+) or 3.12.x (legacy Android)

[nikhiljainlive]

We are facing daily crashes because of this issue. Is there any update on this?

[yschimke]

We don't have a reproduction for this, the suggested one above turned out not to be the case.
