-------------------------------------------
Summary: Build breaks when compiling with JDK 1.8 - Modified Map
Implemententation
Key: JENA-667
URL: https://issues.apache.org/jira/browse/JENA-667
Project: Apache Jena
Issue Type: Improvement
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)
Reporter: Christoph Emmersberger
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}
