> Components: Build
> Affects Versions: Jena 2.11.1, Jena 2.11.2
> Environment: java version "1.8.0"
> Java(TM) SE Runtime Environment (build 1.8.0-b132)
> Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode)

> When running the build with JDK 1.8 (Java 8), the following compilation error
> occurs:
> {code}
> public class OneToManyMap<From, To> implements Map<From, To> {
> ...
> public void remove( Object key, Object value ) {
> List<To> entries = m_table.get( key );
> if (entries != null) {
> entries.remove( value );
>
> if (entries.isEmpty()) {
> m_table.remove( key );
> }
> }
> }
> ...
> }
> {code}
> Seems like the underlying Map implementation has been modified to provide a
> boolean return statement as of JDK 1.8
> {code}
> public boolean remove(Object key, Object value) {
> ...
> }
> {code}
