A DESCRIPTION OF THE PROBLEM :
Under certain circumctances, javac 8 rejects to compile code that compiles under previous versions of javac. In the given example, if non-compiling line is modified to "return this.eq(this.value, value);" or "return super.eq(this.value, value);", the problem goes away.

REGRESSION. Last worked in version 7u51


ERROR MESSAGES/STACK TRACES THAT OCCUR :
 error: no enclosing instance of type AbstractMapF is in scope

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import java.util.AbstractMap;

public class Jdk8Test {

    public static abstract class SingletonMap<K, V> extends AbstractMapF<K, V> {

        private final K key;
        private final V value;

        public SingletonMap(K key, V value) {
            this.key = key;
            this.value = value;
        }

        @Override
        public boolean containsValue(Object value) {
            return eq(this.value, value); // does not compile
        }
    }

    public static abstract class AbstractMapF<K, V> extends AbstractMap<K, V> {
        protected boolean eq(Object a, Object b) {
            return true;
        }
    }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Qualifying instance on which method eq is invoked helps: either "this.eq(...)" or "super.eq(...)" compiles fine.
