The code to produce this error:

  | import org.jboss.cache.pojo.PojoCache;
  | import org.jboss.cache.pojo.PojoCacheFactory;
  | import org.jboss.cache.Fqn;
  | 
  | public class JDBCCacheTest {
  | 
  |     public static final String CONF_FILE = "jboss-cache.xml";
  |     public static void main(String[] args) {
  |         PojoCache cache = PojoCacheFactory.createCache(CONF_FILE, true);
  |         cache.getCache().removeNode(Fqn.fromString("C"));
  |         for (int i = 0; i < 100; i++) {
  |             cache.attach("C/"+ Integer.toString(i), Integer.toString(i));
  |             System.out.println("added "+i+" dummy node to Jboss cache.");
  |         }
  |     }
