[lworld] RFR: 8253873: jdi, jvmti, and jdwp tests fail because of unexpected number of interfaces

[Harold Seigel]

Please review these changes to fix tier4 and tier5 tests that started failing because injected interface IdentityObject
is no longer hidden.  Tiers 4 and 5 were run on linux X64, Macosx, and Windows to check that the tests passed.
