Android studio instant-run not work well

Question

I use the Android studio 2.0, and configure the project with the official doc , the config of instant run in the setting window of AS has changed from disabled to enabled state. As well the run icon has lightning now，but when i change the code, just add a toast in a function, and click the lightning run, the application will be exit, and log show like below:

11-24 19:59:40.382 20951-20957/com.ss.android.essay.joke I/art: System.exit called, status: 1
11-24 19:59:40.383 20951-20957/com.xxx I/AndroidRuntime: VM exiting with result code 1, cleanup skipped.

Edit：The status of bug has updated，crash not happened again with alpha2，but still can't use instant-run， more detail：https://code.google.com/p/android/issues/detail?id=195064

Edit: Android studio 2.1.1 with 2.12 gradle work well now.
