IvyDE 2.2.0.beta1 with Ivy 2.3.0 fails to load multiple Ivy classpath containers in Eclipse

After updating Ivy to 2.3.0 in Eclipse (IvyDE remains at 2.2.0.beta1), and project with multiple IvyDE classpath containers defined in the .classpath file will only load the last one. For example, I have a project set to load conf 'local' for the test libraries as one classpath container and conf 'master' for the main application dependencies as another classpath container (only this container is deployed by WTP).

Only the 'master' container is showing up now. If I comment out the 'master' container in .classpath and Resolve, the 'local' container shows up. So it is not the .classpath XML that has a problem. IvyDE is dropping all but the last container.
