## What is the purpose of the change Apache commons-collections 3.x is a Java 1.3 compatible version, and it does not use Java 5 generics. Apache commons-collections4 4.4 is an upgraded version of commons-collections and it built by Java 8. Because the flink-core use commons-collections 3.x in some old codes, so we currently we can not upgrade it directly. This we add commons-collections4 support first in order to forbid the next and later error usages. ## Brief change log Add commons-collections4 dependency in managed pom. ## Verifying this change Just add dependency in managed pom, it will not cause build error.
