Sebb resolved COLLECTIONS-527. ------------------------------ Resolution: Won't Fix It's not possible to fix this > Please create a version commons-collections 3.x for jdk 8 compatibility > ----------------------------------------------------------------------- > > Key: COLLECTIONS-527 > URL: https://issues.apache.org/jira/browse/COLLECTIONS-527 > Project: Commons Collections > Issue Type: Bug > Reporter: Ignat Alexeyenko > Priority: Blocker > Labels: java8, jdk8 > Attachments: COLLECTIONS_3_2_BRANCH_COLLECTIONS_527.patch > > > Could you make a 3.x or 3.2.x release compatible with JDK8 ? > {code} > org.apache.commons.collections.MultiMap { > public Object remove(Object key, Object item); > } > {code} > is not compatible with JDK's 8 Map > {code} > java.util.Map { > boolean remove(Object key, Object value); > } > {code} > 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: > {code} > 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 > {code} > *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! -- This message was sent by Atlassian JIRA (v6.2#6252)
