问题描述
我不知道在哪里写这个并决定在这里做。
I didn't know where to write something about this and decided to do it here.
在调试我的程序后，我发现调用Driver。 getConnection（string，string，string）挂起调用线程。为什么（？），我真的不知道，但我发现这种情况发生在java 1.6.0_29而不是java 1.6.0_26。
After loooong time debugging my program I could find out that calling Driver.getConnection(string, string, string) hangs the calling thread. Why(?), I really don't know, but I could find out that this happens with java 1.6.0_29 and not with java 1.6.0_26.
完整的环境：
-
操作系统：在redhat 6.1和Windows 2008上测试
OS: Tested on both redhat 6.1 and Windows 2008
驱动程序：MS SQL Server JDBC驱动程序版本3.0.1301.101
Driver: MS SQL Server JDBC Driver version 3.0.1301.101
Java版本：1.6.0_26和1.6.0_29
Java Versions: 1.6.0_26 and 1.6.0_29
正如我之前所说，它适用于1.6.0_26。
As I previously told it works with 1.6.0_26.
有没有人那样做知道可能导致这种情况的原因是什么？也许有些开发者？ ：p
Is there anyone that has any idea what's possibly causing this? Maybe some developer? :p
祝你好运，

推荐答案
我遇到了完全相同的行为：
I encountered exactly the same behaviour:
我在Windows 7 64位PC上同时使用Oracle XE和MS SQL Server Express - 我从1.6.0_27（x64版本）升级到java 1.6.0_29，并且惊讶地看到相同的程序能够连接到Oracle XE但不能连接到MS SQL Server ...
I use both Oracle XE and MS SQL Server Express on my Windows 7 64bit PC - I upgraded to java 1.6.0_29 from 1.6.0_27 (the x64 version) and was surprised to see that the same programs where able to connect to Oracle XE but not to MS SQL Server...
我将问题追溯到 javax.sql.DataSource.getConnection（）它永远挂起的地方 - 因为这只是一个接口，jdbc驱动程序我怀疑...
I traced down the problem to javax.sql.DataSource.getConnection() where it was hanging forever - because this is just an interface, the jdbc drivers raised my suspicion...
我正在使用MS SQL Server JDBC驱动程序3.0.1301.202，我甚至更新到SQL Server CTP（社区技术预览） 4.0.1722.1因为我的怀疑是它必须对jdbc驱动程序做一些事情 - 但没有成功：仍然挂起！
I'm using the MS SQL Server JDBC Driver 3.0.1301.202 and I even updated to SQL Server CTP (the "community technical preview") 4.0.1722.1 because my suspicion was that it has to do something with the jdbc driver - but no success: still hanging!
我的解决方法是降级到1.6.0_27并且 - 爆炸：一切都很好了！
My workaround was to downgrade to 1.6.0_27 and -- bang: everything was fine again!
最好的问候
