>             Project: CloudStack
>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: Install and Setup, Management Server
>    Affects Versions: Future, 4.3.0, 4.4.0
>         Environment: MySQL configured for DB HA
>            Reporter: Adrian Lewis
>            Assignee: Hugo Trippaers
>            Priority: Critical
> When configuring the database HA feature introduced in 4.3, the manangement server fails
to create the DB connection due to the mysql connector jar being loaded using tomcat's common
class loader but the "cloud-plugin-database-mysqlha-4.3.0.jar" is loaded by the webapp class
> The cloud-plugin-database-mysqlha-4.3.0.jar needs to also be loaded from the common class
loader instead of webapp class loader.
> Fix is to declare the cloud-plugin-database-mysqlha-4.3.0.jar under the common.loader
section in /etc/cloudstack/management/
> Only tested using a fresh install on Centos 6.5 and the public repo packages.
> Manual fix provided by Damoder Reddy in users mailing list: "Looks like we did not change
the while refactoring out the mysql connector part"
