@kamilkrzywanski Could you see if I got them all in https://github.com/GuicedEE/Services/tree/master/Google/guice-core ?

@GedMarc Where can I find parent pom to run this project?
UnsafeClassDefiner in my code is renamed to LookupClassDefiner, AnonymousClassDefiner is dead and removed since Unsafe::defineAnonymousClass is removed

Hmm snapshots don't go to central anymore - I'm pushing through RC6, central is a nightmare will ping when up.
I use the github packages

<repository>
    <id>guicedee-github</id>
    <url>https://maven.pkg.github.com/GuicedEE/</url>
    <snapshots>
        <enabled>true</enabled>
    </snapshots>
</repository>

Those are actually better resolutions than I had, I used the private lookups but it looks cleaner

The solution based on https://github.com/GuicedEE/Services/tree/master/Google/guice-core
will most likely not pass the tests.
