As I said: you chose it...
Easier, I don't know. An h2.jar or an XX.jar are still just libs, none is easier than the other for distribution, as long as the underlying DB is stable and use-able.
The only difference is the resulting DB: Either locked to one language, or not.
But what is done is done, it is not so important
I will surely find a way to script the backup the DB properly.
