Plumber AssertionError on startup

[jzbrooks]

Description

The app crashes on startup because of EnumSet reflection in the plumber artifact. R8 shakes all of the relevant fixes.

Reopens #1899 for visibility.

Steps to Reproduce

leakcanaryr8.zip

Build a release apk, install it, and run the app.

Expected behavior: [What you expect to happen]
The app to run and plumber to be setup properly.

Version Information

• LeakCanary version: 2.6
• Android OS version: 11
• Gradle version: 6.7.1

Additional information

#1914 solves the problem, but there might be a slightly more specific rule. It keeps all of the enum cases in perhaps a indirect way. It explicitly keeps the thing that EnumSet depends on, though.

-keepclassmembers,allowoptimization enum leakcanary.AndroidLeakFixes {
    public static **[] values();
}
