Upgrade of the Java version for any library jar file will affect downstream users and is not a decision made without discussion. Ideally a library should be compatible with all Java Long-Term Support (LTS) releases, unless the intended functionality is significantly compromised. The Commons project aims to target Java 8 until the version is end-of-life, or a component's functionality requires a newer Java version.
