使用BoneCp 0.7.1
我设置了我的应用程序，一切正常，但随后数据库脱机。
在下一个应用程序请求getConnection()开始抛出内部异常并启动重试机制但getConnection()从未返回，导致线程挂起。
以下异常会反复抛出，但您希望getConnection()返回NULL或至少抛出SQLException，以便您可以处理它。
这看起来很相似：http://jolbox.com/forum/viewtopic.php?t=339&p=1390但是我的问题在建立连接后出现了。
还看到了...... BoneCP doesn't recover from broken connection 我会尝试8.0-rc1

尝试8.0-rc2同样的问题getConnection（）不会返回。
