Test case:
public class X {
	public static void main(String[] args) {
		boolean b = true;
		Character _Character = new Character(' ');
		char c = ' ';
		Integer _Integer = new Integer(2);
		if ((b ? _Character : _Integer) == c) {
			System.out.println("SUCCESS");
		} else {
			System.out.println("FAILURE");
		}
	}
}

javac can successfully compile it. It converts the _Character to its charValue()
and the _Integer to its intValue().

We fail with:

----------
1. ERROR in C:\tests_sources\X.java (at line 7)
	if ((b ? _Character : _Integer) == c) {
	    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Incompatible operand types Object and char
----------
1 problem (1 error)

Note that it doesn't work anymore if you extract the conditional expression in a
local variable of type Object.
