ManyToOne associations in embeddable collection elements and composite IDs are always eagerly loaded

A regression was introduced when load plans were introduced in 4.3 that results in many-to-one associations to be eagerly loaded if they are embedded in an embeddable collection element.

For example:

	@Entity(name = "Parent")
	public static class Parent {
		@Id
		@GeneratedValue
		private int id;

		private ContainedChild containedChild;

		@ElementCollection
		private Set<ContainedChild> containedChildren = new HashSet<ContainedChild>();
	}

	@Entity(name = "Child")
	public static class Child {
		@Id
		@GeneratedValue
		private int id;

	}

	@Embeddable
	public static class ContainedChild {
		@ManyToOne(fetch = FetchType.LAZY, cascade = CascadeType.ALL)
		private Child child;

		ContainedChild() {
		}

		ContainedChild(Child child) {
			this.child = child;
		}
	}

When a Parent entity is loaded, containedChild.child will be lazy (as expected).

When a Parent#containedChildren is initialized, the child contained in each ContainedChild collection element will be non-lazy. These child entities should be lazy.

I believe that many-to-one associations in composite IDs will also be eagerly loaded, even when mapped as lazy. I need to look into this further though.
