Java Glassfish/Toplink和sqljdbc.jar在断开的数据库连接上永远重试

我将Glassfish和Toplink与MS SQL Server一起使用，因此使用sqljdbc4.jar连接到数据库。当数据库不可用（DB服务器关闭）时，CPU使用率会上升到100%，Glassfish会一直尝试连接。我的日志很快被以下消息填满：

有没有办法为数据库连接设置重试限制，或者在连接重试之间设置暂停超时

如何让Glassfish抛出异常，而不是尝试永远连接？

我们发现，这似乎是Microsoft在sqljdbc4.jar中的一个错误：

GlassFish的HADB版免费提供了一个用于MS SQL的DataDirect JDBC驱动程序，可以处理连接重置和关闭
