jvpp: bugfix for deadlock in java future API (VPP-1037)
- message sending method inside synchronization blocks causes deadlock between sending and receiving part - breaking atomicity of sending message and putting future with corresponding id to map needs additional handling by writer and receiver, regardless which part get access to sync block first will create new future and second one will complete it and remove from map, in case of dump calls where control ping reply is required as confirmation that all information were send, if ping reply is received before writer put future in map, reader will create regular control ping future instead and writer needs to made association between these two futures Change-Id: Id29a19be7a5319291a5e07cf931080610178f00c Signed-off-by: Matej <matej.perina@pantheon.tech>
