ASF subversion and git services commented on CLOUDSTACK-4466:

Commit 28af817fcc835c10e4a21f08e971041325ad206d in branch refs/heads/master from [~davecahill]

CLOUDSTACK-4466: Fix DHCP capability breaks in 4.2 for MidoNet

A recent code change in NetworkManager causes NullPointerExceptions when DHCP
capability list is null.

The commit which made the NetworkManager change also changed the VirtualRouter
to not use null for the capabilitylist, but didn't make this change for other
network devices, causing DHCP to fail on MidoNet.

This change also updates the MidoNet plugin to use the most recent MidoNet API.

> Prior to this change, the default "capabilities" for DHCP list was null.

> The change causes a NullPointerException if the DHCP capabilities list is null. The change
replaces null in the VirtualRouterElement to avoid the NPE, but leaves other elements which
were using null for the DHCP capabilities list broken.
> This causes an NPE and failure to implement DHCP. From a quick code grep, it looks like
MidoNet is the only network plugin affected.
