I looked a bit more closely and no longer think the one-liner will is sufficient, since it will break the behaviour of MethodType.fromMethodDescriptorString:

   public static MethodType fromMethodDescriptorString(String descriptor, ClassLoader loader)
       throws IllegalArgumentException, TypeNotPresentException

    * Finds or creates an instance of a method type, given the spelling of its bytecode descriptor.
    * Convenience method for {@link #methodType(java.lang.Class, java.lang.Class[]) methodType}.
    * Any class or interface name embedded in the descriptor string
    * will be resolved by calling {@link ClassLoader#loadClass(java.lang.String)}
    * on the given loader (or if it is null, on the system class loader).

The observations do suggest there may be some unexpected future surprises in store for bootclasspath code in restricted packages when a SM is enabled. (The more code we can get off the boot classpath the better off we will be.... hopefully Jigsaw FTW!)

It is be better if the jtreg process test did not monkey around with the restricted package list, it's asking for a poke in the eye! 

IMHO we should prioritize fixing the test rather than fixing the lambda code to make that test work.
