Charlie,
Does it look similar to the following bugs?
https://bugs.openjdk.java.net/browse/JDK-8136353
https://bugs.openjdk.java.net/browse/JDK-8169425
If that's the same (and it seems so to me [1]), then speak up and
persuade Paul it's an important edge case (as stated in JDK-8169425).
Best regards,
Vladimir Ivanov
[1] new RubyClass(Ruby.this) in
public static class Ruby {
private ClassValue<RubyClass> cache = new ClassValue<RubyClass>() {
protected RubyClass computeValue(Class<?> type) {
return new RubyClass(Ruby.this);
}
};

So I don't think we ever closed the loop here. Did anyone on the JDK
side confirm this, file an issue, or fix it?
We still have ClassValue disabled in JRuby because of the rooting issues
described here and in https://github.com/jruby/jruby/pull/3228.

Remi, I tried your link with my simplified scenario and it does there
not stop the collection of the classloader
