total is 93.
But with LambdaForm only 2:
[LF_RESOLVE] java.lang.invoke.LambdaForm$Holder identity_L LL_L (success)
[LF_RESOLVE] java.lang.invoke.LambdaForm$Holder zero_L L_L (success)


# for LambdaForm:
# javac -J-verbose HelloWorld.java | grep grep LambdaForm | grep __JVM_LookupDefineClass__
# total is 36.
We collect all the LF_RESOLVE lines when parsing the classlist. At the end of the static dump, we invoke generateDirectMethodHandleHolderClassBytes to generate the DirectMethodHandle$CDSHolder1 class (as well as other holder classes that are currently generated by GenerateJLIClassesPlugin.java.)
