运行Apache Jackrabbit GarbageCollector时出错

Question

我正在尝试使用此链接中提供的方法在我的DataStore上运行GarbageCollector：https://wiki.apache.org/jackrabbit/DataStore

我正在使用Jackrabbit 2.6

public void runGC(){
        LOG.info("Inside runGC() method :: START ");

        DataStoreGarbageCollector gc = null;
        RepositoryManager rm = null;
        try {
            // need to login to start the repository
            rm = DMSRepositoryFactory.instance.getRepositoryFactory().getRepositoryManager((JackrabbitRepository)DMSRepositoryFactory.instance.getRepository());
            session = DMSRepositoryFactory.instance.getRepository().login();
            LOG.info("Inside runGC() method :: before starting Garbage Collector()");

            gc = rm.createDataStoreGarbageCollector();
            gc.mark();
            gc.sweep();
            LOG.info("Inside runGC() method :: after executing Garbage Collector()");
        } catch (RepositoryException e) {
            LOG.error("Error While Runining GC", e); 
            e.printStackTrace();
        }finally {
            LOG.info("Inside runGC() method :: inside finally closing Garbage Collector()");
            gc.close();
        }

        session.logout();
        rm.stop();
    }

在运行代码时，我遇到异常
