Constant lambdas are translated into constant dynamic at least by the javac of Amber, but i do not know if the javac of the jdk11 does that too. 

Otherwise, if you look for classes containing constant dynamic, we use this class [1] that was generated using the javac of Amber when testing ASM. 
If you want a more complex example, you can play with cplisp which encode lisp atoms into the constant pool using constant dynamic [2].
