1. Given a Maven project containing the following file:

import com.google.common.cache.CacheBuilder;
import com.google.common.cache.RemovalListener;
import com.google.common.cache.RemovalNotification;

public class Main {

    public static void main(String[] args) {
        CacheBuilder.newBuilder().
                removalListener(new RemovalListener<String, String>() {
                    @Override
                    public void onRemoval(RemovalNotification<String, String> notification) {
                        notification.getKey();
                    }
                }).
                build();
    }
}

2. Please the caret after "notification." and try triggering code-complete.
3. Nothing will happen (the code complete dialog will not come up).
4. The code compiles fine. There is no evidence of a parsing error in the UI or messages.log. The feature fails silently.

Code-complete works fine on other code. There is just something special going on with this case.

This is reproducible always.
