ArrayIndexOutOfBoundsException: length=8192; index=8192 when using Http2

[mabeijianxi]

We recently upgraded okhttp to 3.12.12 and opened http2. An exception occurred on the line.

Yikes. Might be fixed by grabbing the latest Okio.
"com.squareup.okio:okio:2.8.0"

Not enough information to take action on this otherwise.

[yschimke]

@mabeijianxi any chance of a server and exact details of the mobile device we can reproduce against, otherwise it's unlikely we can reproduce. Please reopen with enough information to reproduce.

@yschimke @swankjesse The phones in question are all vivo, and the system version is 7.1.2, 8.0.0, 8.1.0, 9.0

@swankjesse
I also encountered the same problem, can you tell us the cause of the problem and the progress of the repair?

[swankjesse]

If your see com.android.okhttp in the stack trace you're using a very old OkHttp that's bundled with Android. Try using OkHttp directly which has lots of bugs fixed.

For anyone looking, I had this same issue on OkHTTP 2.9.0. (except my index was negative: java.io.IOException: canceled due to java.lang.ArrayIndexOutOfBoundsException: length=8192; index=-18).

Seems the cache was corrupted or something? I was able to recover by calling Cache.delete() and then recreating the Cache object and retrying.

[odbol]

To anyone finding this, it's probably a multithreading issue or you are using more than one cache object at the same time. Try making the Cache a singleton and accessing from only one thread: #8080
