documentation can/should be improved, but there is something in the
application cookbook.
There is nothing framework-specific to migrations anyway; as many
other feature in the application cookbook, it maps directly to the
deploy resource; its documentation applies.

Except... the Java cookbook does not use deploy at this time; it
didn't in the previous version, and unfortunately it still does not.

It's not very clear to me how migrations would fit in the workflow of
a typical Java shop. In fact I've brainstormed about application_java
with miscellaneous people and we haven't even touched on
migrations--not high-priority enough, I guess.

As for migrations in java flyway and liquibase come into mind:

Don't have a concrete (and chefifyed) example though...

I'm curious: you mention Rails migrations? Do you also have a Rails
app, or do you use it just for managing migrations?
Could you maybe use application_ruby for that part, and then somehow
orchestrate the deployment interactions?
