(Does resolving a LF from a holder does trigger emitting a `@lambda-form-invoker` line when generating the classlist?)

The  `@lambda-form-invoker` lines are generated in MethodHandleStatics.java::traceLambdaForm() when LambdaForms are being resolved:

This is the same place where GenerateLinkOptData.gmk gathers information for generating the Holder classes for the JDK's module image.
