Description brychcy 2015-08-24 09:40:45 UTC 
With Netbeans 8.1 beta (I didn't test with earlier versions), create a java project with the following classes:

=== bug/Nullable.java ===
package bug;

import java.lang.annotation.Documented;
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target({ ElementType.TYPE_USE })
public @interface Nullable {
    // no body
}

==== bug/Bug.java
package bug;

import java.util.function.Consumer;

class Bug {
    Object f() {
        return new Consumer<@Nullable String>() {
            public void accept(@Nullable String t) {}
        };
    }
}


An error is returned with the following Stacktrace:
---------
Caused: java.lang.AssertionError: Could not determine position of tree Consumer<@Nullable() String> within frame new Consumer<@Nullable() String>(){
    
    () {
        super();
    }
    
    public void accept(@Nullable()
    String t) {
    }
}

Actually, the error already happens even if the involved types are unknown:
package bug;

class Bug {
    Object f() {
        return new Y<@X String>(){};
    }
}
