To use JDK17 + DirectByteBuffer, we need to set two JVM options:

--add-opens=java.base/java.nio=ALL-UNNAMED
--add-opens=java.base/sun.nio.ch=ALL-UNNAMED

This PR adds:

  • CI for JDK17
  • Add a workaround even if these JVM options are not set.
  • Add a warning message when DirectByteBuffer is used in JDK17 without setting these JVM options
