Hey @cweitkamp, I just saw this now. I am not really sure if this is worth the effort: 1.x bindings will anyhow always require the compat-layer and it should be easy to include Apache Commons for this legacy code. This won't prevent us from removing Commons from openhab-core.

[cweitkamp]

Yes, I know. And I won't spent more time on it. I just adjusted the API classes as they are the OHC equivalents.
