Subject Artemis 1.5.0 fails to discover libAIO on Linux, falls back to NIO
Date Mon, 12 Dec 2016 16:34:14 GMT
I have a RHEL 6.7 server wich has LibAIO installed, using Java 1.8.0_102

Artemis 1.4.0 finds and uses it with no problem, as this log line shows:
17:18:30,060 INFO  [org.apache.activemq.artemis.core.server] AMQ221012:
Using AIO Journal

When I create a broker with the same parameters on the same machine, but
instead using Artemis-1.5.0 it fills in NIO in the broker.xml; When I change
that by hand to ASYNCIO I get the following in the log:
15:46:04,805 WARN  [org.apache.activemq.artemis.core.server] AMQ222018: AIO
was not located on this platform, it will fall back to using pure Java NIO.
If your platform is Linux, install LibAIO to enable the AIO journal

(I realize that having NIO in the broker.xml itself is a sign that the Linux
AIO library could not be found)

Yum shows that libaio.x86_64-0.3.107-10.el6 is installed.

is this a bug, or some other mismatch I made?
