Use invokevirtual/invokeinterface when generating bytecode to invoke private nestmate instance method
Summary: Prior to nestmate support, invocation of lambda is via REF_invokespecial method
handle for invocation of the lambda body.  invokevirtual/invokeinterface should be used
instead as the lambda proxy classes are defined as a dynamic nestmate.
