Maven Embedder incorrectly resolves properties in multiprojects and incorrectly resolves dependency management for POM dependencies

This was first noticed using IntelliJ embedder - see JIRA's are

• http://www.jetbrains.net/jira/browse/IDEA-17318 - Parent POM properties are not working in child POM's
• http://www.jetbrains.net/jira/browse/IDEA-17320 - Dependency Management section is not cascading correctly

The first issue prevents maven embedder from parsing a child POM that uses a parent POM to set the version of an artifact, if the parent POM using properties to set the version.

The second issue shows even if you set the version explicitly the parent POM's dependency management section does not cascade in embedder (but it does in maven) correctly for POM type dependencies.

I have written a unit test (attached) to embedder to test for this. But am unsure how to fix.
