JEE6 dependencies are not detected correctly when generating WTP settings

JEE6 dependencies (like geronimo-servlet_3.0_spec) are not detected correctly, as a result, the generated WTP file (org.eclipse.wst.common.project.facet.core.xml) uses wrong version (should be 3.0 instead 2.4) for web facet
(<installed facet="jst.web" version="2.4"/>)

Steps to duplicate issue
1. Unzip servlet30app.zip
2. Execute "mvn eclipse:eclipse" in servlet30app folder
3. The generated file .settings/org.eclipse.wst.common.project.facet.core.xml use servlet 2.4 facet (<installed facet="jst.web" version="2.4"/>)

Expected result:

• The version should be 3.0 (<installed facet="jst.web" version="3.0"/>)

Additional information:
I also attached servlet25app.zip which works correctly for JEE5
