java/apache-commons-collections: limit JAVA_VERSION from 8 to 20 because build fails with 21+
Build error with OpenJDK 21:
[javac] /wrkdirs/usr/ports/java/apache-commons-collections/work/commons-collections-3.2.2-src/src/java/org/apache/commons/collections/CursorableLinkedList.java:188: error: addLast(Object) in CursorableLinkedList cannot implement addLast(E) in List [javac] public boolean addLast(Object o) { [javac] ^ [javac] return type boolean is not compatible with void [javac] where E is a type-variable: [javac] E extends Object declared in interface List [javac] /wrkdirs/usr/ports/java/apache-commons-collections/work/commons-collections-3.2.2-src/src/java/org/apache/commons/collections/CursorableLinkedList.java:176: error: addFirst(Object) in CursorableLinkedList cannot implement addFirst(E) in List [javac] public boolean addFirst(Object o) { [javac] ^ [javac] return type boolean is not compatible with void [javac] where E is a type-variable: [javac] E extends Object declared in interface List
New JDK 21 methods in java.util.List addFirst and addLast has a void
return type. This clashes with the existing boolean return from the
same method in AbstractLinkedList.
Upstream fixed this in 4.5.0 only. But this old 3.x branch isn't fixed.
