我的代码点，它在 loadVCard(mucChat.room.asEntityBareJid()) 方法中崩溃

val vCardManager = VCardManager.getInstanceFor(Config.conn1)
        val vCard = vCardManager.loadVCard(mucChat.room.asEntityBareJid())
        val url =  URL("https://www.degraeve.com/images/lotus.jpg")
        val stream = url.openStream()
        Thread.sleep(500)
        val avatar2 = ByteStreams.toByteArray(stream)
        Thread.sleep(500)
        vCard.setAvatar(avatar2,"image/jpg")
        vCardManager.saveVCard(vCard)

谢谢。
