---------------------------------------
Summary: PatriciaTree incompatible with Java 21 (JEP 431 Sequenced
Collections)
Key: COLLECTIONS-888
URL: https://issues.apache.org/jira/browse/COLLECTIONS-888
Project: Commons Collections
Issue Type: Bug
Affects Versions: 4.5.0
Reporter: Marc Carter
JEP431 introduces some new API calls that conflict with method already existing
in {{AbstractPatriciaTree}}
{noformat}
java: lastEntry() in org.apache.commons.collections4.trie.AbstractPatriciaTrie
cannot implement lastEntry() in java.util.SequencedMap
attempting to assign weaker access privileges; was public
{noformat}
Quick fix is simply to make {{firstEntry()}} and {{lastEntry()}} methods
public. I have not assessed any deeper integration with the new API.
Aside: I'm not the first to request *please make {{AbstractPatriciaTree}}
public*! All the advanced users are having to write extensions into the
collections4 package.
