A DESCRIPTION OF THE PROBLEM :
Using the new internal Classfile API to rename a class that includes an Invokedynamic constant pool item, like LambdaMetafactory, does not copy the static bootstrap arguments.

The issue seems to be in the class jdk/internal/classfile/components/ClassRemapper.java

ClassRemapper is doing the following
case InvokeDynamicInstruction idi ->
                        cob.invokeDynamicInstruction(DynamicCallSiteDesc.of(
                                idi.bootstrapMethod(), idi.name().stringValue(),
                                mapMethodDesc(idi.typeSymbol())));

However, this way it ignores the bootstrap arguments. Probably it should be something like this:
case InvokeDynamicInstruction idi ->
                        cob.invokeDynamicInstruction(DynamicCallSiteDesc.of(
                                idi.bootstrapMethod(), idi.name().stringValue(),
                                mapMethodDesc(idi.typeSymbol()),
                                idi.bootstrapArgs().toArray(ConstantDesc[]::new));


FREQUENCY : always
