Master Branch compile failure version issue

The current master branch fails to build locally. The pom file for sample.utility references version 1.2.2, but the actual built artifacts are all version 1.2.1:
https://github.com/eclipse/paho.mqtt.java/blob/8a07b1cc9bde31e3bcbdc86621067a6dc02bc9d7/org.eclipse.paho.sample.utility/pom.xml#L74

This line was introduced with the commit "Update version numbers to 1.2.1", so I'm assuming it's a typo? I don't want to open a PR against master without asking first, though.

Edit: Also, this may silently cause unintented behavior in the future. Maven by default searches central for the corresponding 1.2.2. I'm unfamiliar with how exactly that works, but it may end up mixing the versions together if anyone tries to build this release in the future, after 1.2.2 is actually released.
