activeMQ的一个问题

今天在用mule与activeMQ集成时，启动mule时总停留在activeMQ的启动那里。经过查看源代码发现activeMQ里面出现了一个死循环。

protected void lock() throws Exception {
        lockLogged = false;
        lockAquired = false;
        do {
            if (doLock()) {
                lockAquired = true;
            } else {
                if (!lockLogged) {
                    LOG.warn("Waiting to Lock the Store " + getDirectory());
                    lockLogged = true;
                }
                Thread.sleep(1000);
            }

        } while (!lockAquired && !disableLocking);
    }
protected boolean doLock() throws IOException {
	    boolean result = true;
	    if (!disableLocking && directory != null && lock == null) {
            String key = getPropertyKey();
            String property = System.getProperty(key);
            if (null == property) {
                if (!BROKEN_FILE_LOCK) {
                    lock = lockFile.getChannel().tryLock();
                    if (lock == null) {
                        result = false;
                    } else {
                        System.setProperty(key, new Date().toString());
                    }
                }
            } else { // already locked
                result = false;
            }
        }
	    return result;
	}

在上面的代码中，dolock返回的始终是false。然后你就可以看到lock（）方法就成了一个死循环了。不知道这是activeMQ的问题还是我自己哪里出错。
配置如下：

<amq:broker useJmx="false" persistent="true">
		<amq:persistenceAdapter>
			<amq:amqPersistenceAdapter directory="e:/amq" />
		</amq:persistenceAdapter>
		<amq:transportConnectors>
			<amq:transportConnector uri="tcp://192.168.103.74:61616" />
		</amq:transportConnectors>
	</amq:broker>

最后实在无奈，只好去掉持久化，改成persistent为false。

<amq:broker useJmx="false" persistent="false">
		<!-- <amq:persistenceAdapter>
			<amq:amqPersistenceAdapter directory="e:/amq" />
		</amq:persistenceAdapter> -->
		<amq:transportConnectors>
			<amq:transportConnector uri="tcp://192.168.103.74:61616" />
		</amq:transportConnectors>
	</amq:broker>
