Subject [GitHub] cloudstack pull request: Fix Sync of in Swift
Date Thu, 14 Apr 2016 17:30:29 GMT
Github user jburwell commented on the pull request:
    @rafaelweingartner all statics should ``final`` unless there is explicit handling for
their value changing due to thread safety issues. For loggers, they should always be ``private``
and ``static``.  Log4j provides the means to retrieve the same logger across threads and contexts
by name.  Therefore, if you want 5 classes to share the same logger, retrieve the logger for
that class by name in each class to avoid the potential pitfalls of static shadowing (i.e.
instead of declaring ``private static final Logger LOGGER = Logger.getLogger(MyClass.class)``,
declare it as ``private static final Logger LOGGER = Logger.getLogger(CONSTANT_WITH_THE_NAME_OF_
    As I mentioned in a previous comment, these type of compiler gymnastics are not necessary
to test log output.  Log4j provides the means to attach a custom appender to the logger so
that you can monitor and test output.
