Java - 由于缺少时区信息而导致 UnresolvedAddressException？

Question

我正在寻找几天解决我无法弄清楚的 UnresolvedAddressException 的方法!这似乎是一个非常具有挑战性的问题，因为我什至无法在网上找到其他信息!我在 JamVM 上使用 OSGi 框架。在 Calendar 对象上使用 Date.toString o SimpleDateFormat 时出现此异常。我不明白为什么 bundle 会在 getZoneStrings 函数之后尝试连接。似乎找不到语言环境，但我不确定这是问题所在。我尝试添加文件/etc/timezone(丢失)但它没有解决问题。这是异常的完整堆栈跟踪:

找到 this link其中谈到了通过切换到 Felix 版本 2.0.2 得到解决的类似问题。也许你可以试试看？
