is

this::method

actually leaking when called in

init

or

constructor

blocks?

What do you mean exactly? Can you show us some code?

addMessageHandler(GatewayHello::class.java, this::onHello)
        addMessageHandler(GatewayAck::class.java, this::onGatewayAck)
        addMessageHandler(GatewayInvalid::class.java, this::onGatewayInvalid)
        addMessageHandler(GatewayReconnect::class.java, this::onGatewayReconnect)

Basically, this snippet implies that when an object of that particular type is passed to coroutine channel (they're all children of

Request

), that particular callback must be called. Note that this is only called in

init

block.
