According to [1], we ended support for JDK 1.5 in POI 3.11-beta 1. We added commons-logging, commons-codec, and log4j in that version, so maybe those libraries required Java 6+. None of our current dependencies require Java 7 yet.

We switched off of Windows XP weeks before Microsoft ended support, and switched to Java 7 only 18 months ago. We finally upgraded to 64-bit Oracle JRE 7 so that people can run applications using POI with more than 1024 MB max heap. This was a big deal because 1GB heap can read up to 4MB Excel files using XSSF.
