Under Deprecated there is: "A deprecated interface may be removed from the project after four minor and/or major releases."
http://wiki.apache.org/db-derby/ForwardCompatibility#head-b94fc1d3af5d38a917e2b6c754a8c4213e28f06e Not sure that really works. With an open source project there could be four releases in a couple of months, would allow features to be deprecated very quickly. Not sure of any better wording. Dan.
