Subject [jira] [Commented] (HADOOP-7362) Create a Lock annotation to document locking (hierarchies) for methods
Date Tue, 07 Jun 2011 17:00:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7362?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13045536#comment-13045536

Todd Lipcon commented on HADOOP-7362:

I like the idea of using JCIP where possible, especially for its documentation value.

But in code paths that aren't hot/performance sensitive, please let's not rely on things like
static analysis and @CheckForNull to catch bugs. Good old fashioned asserts and checks like
Preconditions.checkNotNull() have the nice side effect that anyone running tests will find
the bug, and you can't just ignore it like you can static analysis results :)
