With Java5-style loops over collections wrapper types can be unboxed into primitive types. For example:

	void print(List<Integer> list) {
		for (int i : list) { // <-- Warning missing here
			System.out.println(i);
		}
	}

If boxing warnings are enabled a warning should be issued in this situation.

This was reported before in bug #85518 together with two other scenarios (with arrays instead of collections). The array case seems to be fixed.

Reproducible: Always

Steps to Reproduce:
1. Enable Compiler Warning "boxing and unboxing" conversions
2. Paste the following snippet into an Java editor

	void print(List<Integer> list) {
		for (int i : list) { // <-- Warning missing here
			System.out.println(i);
		}
	}

3. No warning is given at the line where the Integer elements of the list are unboxed into primitive int.
