Describe the bug a compiler error fired when make io.vertx.core.Handler to a structural interface

To Reproduce Steps to reproduce the behavior: `package extensions.io.vertx.core.Handler;

@Extension @Structural public class MyHandlerExtension { }`

Expected behavior

Hi @jinwik. In your example you have:

@extension
@Structural
public class MyHandlerExtension {
}

With extension should be Extension by importing manifold.ext.rt.api.Extension. Just want to make sure this is not just a typo.

[jinwik]

This is not a typo; it might be an issue with the GitHub editor. I will create a minimal reproduction scenario.

[rsmckinney]

@jinwik Is this still an issue for you?

[jinwik]

there is not an issue when upgraded to v2023.1.19

[jinwik]

@rsmckinney If such an error(An unknown compilation problem occurred) is found again, how to debug? thx

[rsmckinney]

If it happens again (let's hope not) your best bet is to report the issue here. Debugging this type of problem involves debugging the javac compiler, which steps into and out of manifold code and understanding how it may have manifested. It can get a bit gnarly. Not suggesting you lack the chops, just saying it's probably best if you just throw it over the wall to me.
