> We observed that several tests in this class are taking minutes when they should be taking a few seconds at most. After some debugging, we determined that the JVM itself is struggling to deal with having 100K+ classes loaded. They are loaded because the test is repeated starting and stopping the http service, which creates a classloader and causes soft references to all of the loaded classes to be cached.
> By setting a flag to clear the soft references faster, the test times go back to normal.
