/**
 * This class exists because the JNDI API set wisely uses java.util.Properties
 * which extends Hashtable, a threadsafe class. The NamingParser uses a static
 * instance, making it a global source of contention. This results in
 * a huge scalability problem, which can be seen in ECPerf, as sometimes half
 * of the worker threads are stuck waiting for this stupid lock, sometimes
 * themselves holdings global locks, e.g. to the AbstractInstanceCache.
