RFR JDK-8214700: Compilation fails when extend and implement same method signature with generics

[B. Blaser]

Note that this fix works independently from JDK-8207224 and should be
applied as the current behavior for the inherited implementation of an
erased signature isn't orthogonal to the behavior for the direct
implementation.
Reverting the fix for JDK-8207224 would only remove some side-effects
in some marginal cases (see my JBS comment), as expected?

Shouldn't we go ahead with this one independently from JDK-8207224?
