Do you have the HornetQ AIO native library available as well? See the documentation for more details.
Also, the screenshot you took indicates you are using HornetQ 2.5.0.SNAPSHOT rather than 2.4 as you indicated.
I tried replying yesterday but had an issue with max limits. Anyway I used the native AIO libraries from 2.2.14 . Are they compatible ?
I would expect them to be compatible.
