Research direction

Start with the supplied stack trace, especially android.inputmethodservice.IInputMethodWrapper.setSessionEnabled and com.android.internal.view.IInputMethod$Stub.onTransact. Reproduce the RuntimeException and trace the null value to identify a confirmed fix; done means the binder call no longer produces the reported NullPointerException and the behavior is covered by a regression test.
