					"body": "OK, so after a little thinking, I believe I know what is causing this. I couldn't test on an emulator because there's no bluetooth, but the stack trace jogged a few thoughts. My guess here its that the dynamic proxy class we're generating for the anonymous instance of the LeScanCallback is being asked for it's hashcode. Our dynamic function invoker looks for an override method in the JS code for any method, and if it doesn't exist, it returns a null return value. So in this case, it's looking for a hashcode method on the LeScanCallback, sees none and returns null - but hashcode has to return a primitive int; so Java chokes.\r\n\r\nSo the question here is: what the heck should be do about the base Object methods: hashCode(), equals(), toString() on anonymous implementations of interfaces if the user doesn't provide a JS implementation? \r\n\r\nThis may provide some clues: https://javaclippings.wordpress.com/2009/03/18/dynamic-proxies-equals-hashcode-tostring/",
