A DESCRIPTION OF THE PROBLEM :
Using the "ternary expression" in conjunction with java.lang.Integer can cause invalid bytecode generation

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Using the "ternary expression" as nullcheck, see test-case

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Every test should run without errors
ACTUAL -
testIntegerHashCode and testIntegerBox throwing a NullPointerException

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import org.junit.Test;

public class Ternary {
@Test
public void testObjectHashCode() {
Object o = null;
Object r = (null == o) ? o : o.hashCode();
}

@Test
public void testIntegerHashCode() {
Integer o = null;
Object r = (null == o) ? o : o.hashCode();
}

@Test
public void testIntegerBox() {
Integer o = null;
Object r = (null == o) ? o : -o;
}
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Just don't use the "ternary expression"
