Smack Omemo - When OmemoManager initialize and send publish bundle to service, read response stram, throw EOFException

Step
1.connection.login()

Observable.create<Boolean> {
            SignalOmemoService.acknowledgeLicense()
            SignalOmemoService.setup()
            OmemoConfiguration.setFileBasedOmemoStoreDefaultPath(File(PathManager.getOmemoStorePath()))

            mOmemoManager = OmemoManager.getInstanceFor(connection)

            mOmemoManager?.addOmemoMucMessageListener(this)
            mOmemoManager?.addOmemoMessageListener(this)

            mOmemoManager?.initialize()

            mPerManager = PEPManager.getInstanceFor(connection)
            mPerManager?.addPEPListener(this)

            it.onComplete()
        }.subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe {

                }
