Blocker Description
Could you make a 3.x or 3.2.x release compatible with JDK8 ?
org.apache.commons.collections.MultiMap {
public Object remove(Object key, Object item);
}
is not compatible with JDK's 8 Map
java.util.Map {
boolean remove(Object key, Object value);
}
This causes bugs in projects, who run jdk8 and even compilation failures - for these, who implement common's MultiMap.
Compilation Error
If anyone implement MultiMap in their code, compilation fails with the error:
MyMultiHashMap.java:[11,7] error: remove(Object,Object) in MultiHashMap cannot implement remove(Object,Object) in Map [ERROR] return type Object is not compatible with boolean
Reasoning
JDK 8 is here and being adopted. collection-commons are not yet compatible with Java 8. For many big project switch to commons-collections 4.x is not an option - some transitional release version needs to be required.
Alternative would be for companies to fork commons-collections and create their internal artifact. Why do it if the official compatibility version can be created?
Thanks!
