How to fix "Bad notification" error happening because of "Couldn't inflate contentViews java.util.ConcurrentModificationException"?

Question

Few crashes are being reported in my production android app with the following stack traces. I tried googling and search through StackOverflow but could not figure out what might be causing it. From the looks of the exception being reported, should I serialize the code posting notification from my android app?

Fatal Exception: android.app.RemoteServiceException: Bad notification(tag=null, id=100) posted from package a.b.c, crashing app(uid=10892, pid=2909): Couldn't inflate contentViewsjava.util.ConcurrentModificationException
