RFR: 8265796: vmTestbase/nsk/jdi/ObjectReference/referringObjects/referringObjects002/referringObjects002.java fails when running with JEP 416 [v4]

[Leonid Mesnik]

> The nsk.share.jdi.TestClass1 is used via reflection. The reflective call creates MethodHandle and one more reference to TestClass1.  So the number of expected references should be incremented.  Thanks to @plummercj and @mlchung for the investigation.
> This fix also prints references to inspected class.
