The proposed way to bypass is to store the MethodType as its descriptor string in the bootstrap method arguments, and use MethodType.fromMethodDescriptorString to restore the arguments, which does not have this restriction and does not eagerly load the parameter classes. This case isn't covered by existing tests, so a new test has been added.

I'm wary about the subtle semantic differences that might result from that and would be more comfortable reverting this behavior to what we did before JDK-8332457. Perhaps even backing that one out and re-examine the changes with less urgency.
