> The following block in the loadGlobals() method:
>         // let system properties override other globals
>         try {
>             fromProperties(new HashMap(
>                 AccessController.doPrivileged(
>                     J2DoPrivHelper.getPropertiesAction())));
> retrieves a Properties object from System.getProperties(), which is passed to HashMap's ctor.  The ctor interacts with an enumerator associated with the Properties object to populate the new HashMap instance.  However, if another thread mutates the JVM's System Properties, it can result in a ConcurrentModificationException as observed below:
> Caused by: java.util.ConcurrentModificationException
>     at java.util.Hashtable$Enumerator.next(Hashtable.java:1256)
>     at java.util.HashMap.putAllForCreate(HashMap.java:566)
>     at java.util.HashMap.<init>(HashMap.java:310)
>     at org.apache.openjpa.lib.conf.ConfigurationImpl.loadGlobals(ConfigurationImpl.java:189)
