Nick Hill 30a02b441a Avoid implicit allocations in Http2FrameLogger when logging is disabled (#7937) ... Motivation: Integer autoboxing in this class (and possibly also the varargs arrays) showed non-negligible CPU and garbage contribution when profiling a gRPC service. grpc-java currently hardcodes use of Http2FrameLogger, set at DEBUG level. Modifications: Wrap offending log statements in conditional blocks. Result: Garbage won't be produced by Http2FrameLogger when set to a disabled logging level.		2018-05-15 09:06:32 +02:00
