TCP Endpoint - using SpEL in Spring 3.1 to convert byte[] to byte[] - high cpu load and handle time delay

        Details

          Description

          Configured tcp endpoint with tcp-gateway and simple service activator, which takes byte array as an argument. Transfer large binary files through the the endpoint (incoming). Using ByteArrayLengthHeader as serializer/deserializer.
          Using function

          public byte[] handleBinary(byte[] msg)

          for service activator.
          During transfer of binary files very high cpu load and there is a large tome gap between spring-integration activator functions eg.

          Caused by using in Spring 3.1 automatic conversion for SpEL arguments, which SI is using. Details with a solution from garry russel in the reference URL post.
