Hi All,

We just submitted a JEP draft https://bugs.openjdk.java.net/browse/JDK-8203434.  The proposal is to enhance the Java Socket API to support Remote Direct Memory Access (RDMA) using the rsocket protocol on the Linux-based platforms.

This latest version looks very good. Just a few minor minor comments that I did not noticed before.

  1. What is the behavior on platforms that do not support RDMA? For example, will jdk.net.Sockets::openRdmaSocketChannel throw UnsupportedOperationException? If so, then maybe make that clear in the API sketch in the description.

  2. Links to external references seem to have been inadvertently dropped. Prefer markdown links, e.g.

    ... form Wikipedia ...
