Closing all open streams in GRPC-Java from client end cleanly -

i using grpc-java 1.1.2. in active grpc session, have few bidirectional streams open. there way clean them client end when client disconnecting? when try disconnect, run following fixed number of times , disconnect can see following error on server side (not sure if caused issue though):

disconnect client

while (!channel.awaittermination(3, timeunit.seconds)) { // check upper bound , break if } channel.shutdown().awaittermination(3, timeunit.seconds); 

error on server

e0414 11:26:48.787276000 140735121084416 ssl_transport_security.c:439] ssl_read returned 0 unexpectedly. e0414 11:26:48.787345000 140735121084416 secure_endpoint.c:185]        decryption error: tsi_internal_error 

if use shutdownnow() more aggressively shutdown rpc streams have. also, need call shutdown() or shutdownnow() before calling awaittermination().

that said, better solution end rpcs gracefully before closing channel.
