RCP中的Eclipse控制台缺少输出

在我的RCP中，我展示了控制台，并希望输出不同类别的输出（不仅仅是STDERR和STDOUT） . 我查看并使用了以下代码：

Writing to the Eclipse console

我按照规定执行所有操作：使用ConsoleManager查找或创建控制台，创建视图，显示视图 . 我进行了设置，因此有一些日志写入的“类别”，每个类别对应于存储在IConsoleManager中的不同控制台 .

问题是，输出很少/不可预测地进入控制台：当创建每个新控制台时，我在其上写一条消息 . 这仅在调试期间出现 . 所有其他游戏机似乎都已创建但从未写入 . 除非我把所有东西都写到STDERR（！？） .

下面的代码就是我所做的：

有任何想法吗？
