java.nio.BufferUnderflowException when running Flank for Android with Espresso 3.4.0 with compilSdkVersion 31

[dmitry-ryadnenko-izettle]

When running flank firebase test android run --config my.config.file.yml. Works with project compiled with API level 30 and Espresso 3.3.0. Fails when project has API level 31 and Espresso 3.4.0. And it looks like it happens only with obfuscated code. Is this known? Flank v21.11.0.

@dmitry-ryadnenko-izettle Hey, please report this issue upstream to LinkedIn. https://github.com/linkedin/dex-test-parser/issues

[dmitry-ryadnenko-izettle]

Ok, it looks like there is already an issue with this reported there https://github.com/linkedin/dex-test-parser/issues/70.

[dmitry-ryadnenko-izettle]

That one was closed. Created a new one https://github.com/linkedin/dex-test-parser/issues/72.

[BenedictP]

With the 2.3.4 release of dex-test-parse the issue should be fixed:

• https://github.com/linkedin/dex-test-parser/pull/73

[dmitry-ryadnenko-izettle]

@bootstraponline I've made a PR with the fix. I don't want to sign the CLA, I'm not sure if it's allowed in our company to do such things. So, can you please make a copy of my PR instead?

[dmitry-ryadnenko-izettle]

The fix is just a bump of dex-parser. But we are blocked in several directions of our work without this fix to the Flank.

Hi @bootstraponline my team are also affected by this Exception when upgrading to SDK 31 it will be great to the PR @dmitry-ryadnenko-izettle raised incorporated. Thank you for working to resolve this 👍

[bootstraponline]

Hey, thanks for the comments. I merged the fix. A few unrelated deps are causing problems, once I debug that I'll push a new release.

Please share your feedback with Sam Phillips (new FTL product manager) on the Firebase Test Lab Slack. I'm encouraging Google to sponsor a dev to work full time on maintaining the open source FTL ecosystem. That'll significantly improve the response time for issues like this.
