I previously added a helper that started a MockLogAppender to ensure it
was never added to a Logger before it was started. I subsequently found
the opposite case in RolloverIT.java where the appender was stopped
before it was closed, therefore creating a race where a concurrently
running test in the same JVM could cause a logging failure. This seems
like a really easy mistake to make when writing a test or introduce when
refactoring a test. I've made a change to use try-with-resources to
ensure that proper setup and teardown is done. This should make it much
harder to introduce this particular test bug in the future.
Unfortunately, it did involve touching a lot of files. The changes here
are purely structural to leverage try-with-resources; no testing logic
has been changed.
