Hello,

I’ve implemented Milo OPC UA server 0.6.5 into a product. The server started with Milo 0.6.3 and was recently 0.6.5.

When the server is run on an AMD64 architecture, it runs fine. When I run the server on an ARMHF-32 platform, I see a warning message posted. Both platforms are running Azul's Java 8.

Might someone please provide some insight why this warning is occurring only on a specific platform.

Even with this warning, the server appears to work fine but I'm wondering if I've missed something and if this warning is of any concern.

Sincerely,

Bryce
