在
Ubuntu 12.04下启动IBs TWS时出错。我抬头查看标准输出，发现以下日志消息。我检查了语言环境和tz设置，但无法解决。

解决方案是重新安装OpenJDK并清除当前 java 安装的所有文件。我只是偶然发现的。所以希望这有助于其他人节省一些时间。
sudo apt-get purge openjdk-* icedtea-* icedtea6-*
sudo aptitude install openjdk-7-jdk
原因至今尚不清楚。我还尝试删除所有TWS设置，但这不起作用。引用的TWS.xml（在某些论坛中也找不到）。
我知道
这是一个非常古老的问题，但由于它不为人所知（足够），我想补充一点，OpenJDK没有被IB/TWS支持。您必须使用 Oracle JDK。
