As Nishant already pointed out in the comments, you've found a bughere.
正如 Nishant 已经在评论中指出的那样，您在这里发现了一个错误。
This bug initially was reported in 2004 (>9 years ago!?!!)and this bug seems not to be fixed very soon(or ever). I tested it on several Eclipse version, even on Eclipse Juno SR2, and the bug is still there.
这个错误最初是在 2004 年（> 9 年前！？！！）报告的，这个错误似乎不会很快（或永远）被修复。我在几个 Eclipse 版本上测试过它，甚至在Eclipse Juno SR2 上，但错误仍然存在。
