【问题描述】：
在 arquillian 中运行测试用例时，我遇到了以下错误。 当我在实际服务器上运行用例时，没有出现此类异常。
我正在使用带有 Infinispan 5.1 的 JBoss AS 7。
我尝试使用How to fix "Unable to acquire lock after 15 seconds" errors in Wildfly 的解决方案，但没有成功。

【问题讨论】：
-
获取锁通常会超时，因为另一个线程在持有锁时被阻塞在做某事。您需要在发生这种情况时获取线程转储，并查看其他线程在做什么。
-
您是否能够修复它，知道如何重现此问题。我在做 put 时遇到了同样的错误。但无法重现这一点，因为它很简单，不确定它如何花费超过 10 秒。
