JBossEntityResolver.loadClasspathResource causes NPE when running via JNI
-------------------------------------------------------------------------

                 Key: JBCOMMON-87
                 URL: https://jira.jboss.org/jira/browse/JBCOMMON-87
             Project: JBoss Common
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: common-core (2.x)
    Affects Versions: 2.2.13.GA
         Environment: windows xp 32-bit, MS Visual C++ 2008,  eclipse 3.4.2 with Java(TM) SE Runtime Environment (build 1.6.0_06-b02)
            Reporter: steve bucknam


I created a C++ program the invokes a Java method via JNI.  The classpath is setup to include all required JBoss Cache 3.1.0 jars including JBoss Common.  This method instantiates JBoss Cache as follows:

	    	CacheFactory<String, String> aFactory = new DefaultCacheFactory<String, String>();
	    	Cache cache = aFactory.createCache(configFile);

This causes a NullPointerException in JBossEntityResolver.loadClasspathResource().  The code is as follows:

    ClassLoader loader = Thread.currentThread().getContextClassLoader();
    URL url = loader.getResource(resource);

The ContextClassLoader will always be null when run within JNI.
