I am experiencing a problem which seems to be coming from the recent re-factorings i.e. Bug 360301, Bug 350385 and Bug 305782

  After installing latest Mylyn Reiews, the Eclipse installation is not starting and is complaining of a class not found exception, so the TasksUIPlugin can not be started.

Caused by: java.lang.NoClassDefFoundError: org/eclipse/mylyn/internal/tasks/core/notifications/Environment
	at java.lang.Class.getDeclaredConstructors0(Native Method)
	at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389)

	at org.eclipse.osgi.framework.internal.core.AbstractBundle.loadBundleActivator(AbstractBundle.java:166)
	... 69 more     

Looking at the latest changes in Tasks core, it can be seen that the class above was removed from o.e.m.tasks.core 
  However the upgraded installation picked up the new tasks.core plug-in but not the latest o.e.m.tasks.ui plug-in.

Looking at the o.e.mylyn.taks.ui manifest, it specifies dependencies to o.e.m.tasks.core [3.0.0, 4.0.0).  

I think the minimum dependency should now be moved to 3.7
so the latest tasks.ui gets loaded as well.

A separate task shall also be raised to make sure Mylyn Versions and Mylyn Reviews introduce dependencies at the feature level to make the propagation of dependencies more robust.
