Why would this ever be NULL?

[youngki, 2012/10/01 18:51:41]

You had a concern in the previous comment (See patch 'E') that you want to add a
test if BluetoothAdapter* returned is in fact a BluetoothAdapterChromeOs and not
some other object. This will be null if BluetoothAdapter* returned is not
BluetoothAdapterChromeOs*.

[keybuk, 2012/10/01 20:34:37]

No it won't, a static_cast always succeeds - you're thinking of dynamic_cast

[youngki, 2012/10/01 21:03:28]

You are right; I meant to use dynamic_cast. And actually it seems dynamic_cast
is not allowed since it throws compile error saying dynamic_cast not permitted
with -fno-rtti.

I think it's okay to leave the test without this check.. I think if
adapter.get() is something other than BluetoothAdapterChromeOs, this test will
fail on the next line because only BluetoothAdapterChromeOs inherits
BluetoothAdapterClient. I removed ASSERT_TRUE from this test and also
bluetooth_adapter_device_chromeos_unittest.cc.
