/**
 * This method obtains a global ThreadLocal class independent of the classloader (JVM-scope singleton).
 * The easiest solution is to use System.getProperties().get/put, but this solution violate
 * Properties contract and have other drawbacks.
 * <p>Current solution relies on the idea behind
 * {@link org.springframework.beans.factory.access.SingletonBeanFactoryLocator}. See also bug #4648
 *
 * @return Global ThreadLocal (JVM-scope singleton).
