java.lang.VerifyError after upgrading from 1.1.0-alpha06 to 1.1.0-alpha07

See original GitHub issue

After upgrading from com.google.android.material:material:1.1.0-alpha06 to com.google.android.material:material:1.1.0-alpha07, we are getting the following error. It happens in Android 4.3 and Android 4.4 so far.

java.lang.VerifyError: 
  at com.google.android.material.tabs.TabLayout.createTabFromPool (TabLayout.java:862)
  at com.google.android.material.tabs.TabLayout.newTab (TabLayout.java:852)
  at com.google.android.material.tabs.TabLayout.populateFromPagerAdapter (TabLayout.java:1474)
  at com.google.android.material.tabs.TabLayout.setPagerAdapter (TabLayout.java:1465)
  at com.google.android.material.tabs.TabLayout.setupWithViewPager (TabLayout.java:1378)
  at com.google.android.material.tabs.TabLayout.setupWithViewPager (TabLayout.java:1339)
  at com.google.android.material.tabs.TabLayout.setupWithViewPager (TabLayout.java:1319)
  at com.yocto.wenote.note.NoteFragment.initTabs (NoteFragment.java:343)
  at com.yocto.wenote.note.NoteFragment.lambda$onCreateView$1 (NoteFragment.java:199)

This is the code being called just before entering com.google.android.material.tabs.TabLayout

tabLayout.setupWithViewPager(viewPager);

It happens in line 862. (Left side is alpha07, right side is alpha06)

Any idea why such incident happens?

We somehow workaround this problem by adding the following for R8

# VerifyError in Android 4
# https://github.com/material-components/material-components-android/issues/397
-keep class com.google.android.material.tabs.TabLayout$Tab {
*;
}

No crash so far. But, why this is required?

Also receiving this error on Android 4.4, 4.1, 4.2, 4.3 and 5.01. Will try the workaround.
