A DESCRIPTION OF THE PROBLEM :
Collection.removeIf() returns true even though no element gets deleted from the collection.


REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
    @Test
    public void testRemoveIf() {
        class A {
            String s;
            int i;

            A(String s, int i) {
                this.s = s;
                this.i = i;
            }

            @Override
            public int hashCode() {
                final int prime = 31;
                int result = 1;
                result = prime * result + i;
                result = prime * result + ((s == null) ? 0 : s.hashCode());
                return result;
            }

            @Override
            public boolean equals(Object obj) {
                if (this == obj)
                    return true;
                if (obj == null)
                    return false;

                        return false;
                } else if (!s.equals(other.s))
                    return false;
                return true;
            }
        }

        Set<A> set = new HashSet<>(Arrays.asList(new A("one", 1)));
        assertEquals(1, set.size());
        set.iterator().next().s = "two";
        assertTrue(set.removeIf(e -> e.i == 1));
        assertEquals(1, set.size());
