error on Android 4.4 , 5.1 , 6.0

[tstr007]

This is a useful library , however using it on Android 4.4 , 5.1 , 6.0 versions leads to an error java.lang.NoSuchMethodError: No virtual method getBoolean(Ljava/lang/Object;J)Z in class Lsun/misc/Unsafe; or its super classes (declaration of 'sun.misc.Unsafe' appears in /system/framework/core-libart.jar) . It works fine on higher versions. I've seen that this error is related to fabianterhorst:fast-serialization library. Hope you can do something about it .
