-----------------------------------------

             Summary: GridToStringBuilder is broken for classes with inheritance
                 Key: IGNITE-10301
                 URL: https://issues.apache.org/jira/browse/IGNITE-10301
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.7
            Reporter: Alexey Goncharuk
             Fix For: 2.7


Given the following class hierarchy
{code}
    /** */
    private static class Parent {
        /** */
        private int a;

        /** {@inheritDoc} */
        @Override public String toString() {
            return S.toString(Parent.class, this);
        }
    }

    /** */
    private static class Child extends Parent {
        /** */
        private int b;

        /** {@inheritDoc} */
        @Override public String toString() {
            return S.toString(Child.class, this, super.toString());
        }
    }

    private static class Wrapper {
        /** */
        @GridToStringInclude
        Parent p = new Child();

        /** {@inheritDoc} */
        @Override public String toString() {
            return S.toString(Wrapper.class, this);
        }
    }
{code}
the next test fails:
{code}
    /**
     */
    public void testHierarchy() {
        Wrapper w = new Wrapper();
        Parent p = w.p;

        String wS = w.toString();
        String pS = p.toString();

        // Expect wS to be "Wrapper [p=" + pS + ']'.
        assertEquals("Wrapper [p=" + pS + ']', wS);
    }
{code}

{code}
Expected :Wrapper [p=Child [b=0, super=Parent [a=0]]]
Actual   :Wrapper [p=Parent [a=0]Child [b=0, super=]]
{code}

This is a regression from IGNITE-602. We need to fix this in 2.7 or revert IGNITE-602.
