The LogcatExtractionCallable redacts PII web addresses and other data. But it also redacts the names of anonymous inner classes and the file-line information from stack traces.

As an example, this is from a collected logcat, where some critical method names are redacted:

01-27 08:51:58.136 29951 29951 E cr_ChildProcessConnect: Failed to setup connection.

This is what the un-redacted stacktrace should look like:

Something probably needs to be adjusted in this regexp: https://cs.chromium.org/chromium/src/chrome/android/java/src/org/chromium/chrome/browser/crash/LogcatExtractionCallable.java?q=webaddress.elided&sq=package:chromium&dr=C&l=79
