             Summary: Dynamic Classloader still can't keep proper track of jars
                 Key: ACCUMULO-1507
             Project: Accumulo
          Issue Type: Bug
          Components: start
    Affects Versions: 1.5.0
            Reporter: John Vines
             Fix For: 1.5.1

>From ACCUMULO-1321-
It was never quite fixed, it seems. There are two standing issues with the Dynamic Classloader
# if you delete and drop in a new jar, it's possible that the delete only triggers, causing
any classes in the new jar to fail to load unless the file gets renamed in the ext directory
# if you rename the file in the ext directory, it's still possible that the class files fail
to load

I'm speculating there are race conditions around the Monitor being used to watch the file
system, but that is just speculation.
