seems you have the right reference then if your xaDb is actually bulkerXA.
Think you should share your project on github - or a simpler version
showing the issue (a servlet we hit triggering a method logging the number
of connection is fine but please do the setup with tomee maven plugin just
using a placeholder for mysql connection to ensure we are using the exact
same setup than you and that we use the datasource as you).
