Steps to reproduce the problem:
I'm an Android developer whose app uses WebView.

There is a new logcat "error" message since 56.0.2924.23 or so.

Bo Lio here: https://bugs.chromium.org/p/chromium/issues/detail?id=647291#c35 thought that it should be appear in the logcat.

What is the expected behavior?

What went wrong?
Spruous (to me, an outsider) error message in logcat.

Did this work before? N/A 

Chrome version: 56.0.2924.23  Channel: beta
OS Version: 6.0
Flash Version: N/A

Noticed in version 56.0.2924.23. Wasn't there 2-3 weeks ago, I don't think.
