NullPointerException while compiling if "import android.databinding.DataBindingUtil"

I am using DataBinding, I used to write like this(it works fine without errorprone):
ActivityMainBinding binding = DataBindingUtil.setContentView(this,R.layout.activity_main);
After import android.databinding.DataBindingUtil , NullPointerException will be thrown while compiling with errorprone.
It works fine if I change the DataBinding method to this (remove import android.databinding.DataBindingUtil):
ActivityMainBinding binding = ActivityMainBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
Could anybody tell me why there is conflict using errorprone and DataBindingUtil at the same time?
I made a simple sample , it might be help. Also my Android Studio is 3.0.1, gradle is 4.4.1, gradle plugin is 3.0.1.
Thanks!

@tbroyer sorry, my mistake.
I comment out the exception code, and replace with the right code before. I've changed it, should be reproduced now. I'm sure there is a bug although I don't know which side it comes from. Please fetch the updated code and try it again. Thanks.

Please report the issue to Error Prone; this is not a bug in the net.ltgt.errorprone plugin: https://github.com/tbroyer/gradle-errorprone-plugin#troubleshooting
