I'd add a few more caveats. - Not all Spring projects seem to receive equal love. They can and do stomp on each other. - Spring's get-going-quickly seems to mostly come from serious design assumptions. Which is fine per se but they are not made clear which is not OK. - Spring is far too automagical. My latest bugbear is it deciding to change defaults depending on what it thinks I want. Bonus points for there being multiple settings that control the same behaviour only one of which can override. You're not using Java anymore you're using Spring.
