Do you have any numbers? 1M is a lot bigger then 64K, but real world
numbers would be helpful.
I guess the relevant case in question is with Facebook patching the
limit of 65,000 classes in Android :
https://m.facebook.com/notes/facebook-engineering/under-the-hood-dalvik-patch-for-facebook-for-android/10151345597798920
Is that the correct link? That seems to be an issue with an internal
buffer size, not the limit on the number of classes.
