Subject [jira] [Commented] (OAK-37) Use nullability annotation to enforce/document API contract
Date Wed, 16 May 2012 11:31:02 GMT

    [ https://issues.apache.org/jira/browse/OAK-37?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13276668#comment-13276668

Julian Reschke commented on OAK-37:

bq. FindBugs annotations sound good to me as long as they don't introduce a mandatory runtime
dependency on the code (which I don't think they do).

For intra-subproject checking they are only needed at compile time. However, I'm not sure
how it will work when we use a JAR from another subproject. But let's start simple.

bq. IDE support (IntelliJ, Eclipse, etc.) is nice, but IMHO not essential. The important bit
is that we're able to configure our Maven build to check such annotations and fail the build
if the explicitly declared rules are broken.

That should be possible but maybe I'll need some hand-holding with that.

> In a discussion about exception handling on the dev list [1] Julian brough up the idea
of using nullability annotations in APIs. I think we should decide on which one to use and
start using them whereever apropriate.
