有一个discussion on Oracle forums关于这被提升到OTN支持，但没有提到反应。

17.6.2014的更新：现在有一个forum posting添加到该网站解释以下：

Those Java Code Conventions were written in 1999 and have not been
maintained since.

The information might not be up to date; links within the documents
might not work. That is why the pages were removed. Unfortunately
there are other sites that point to that document which were not
updated.

To avoid confusions we have re-posted the original document –with an
appropriate disclaimer about the information not being up to date-
while we clean up those other sites.

Try 07004

确实，似乎页面已经恢复。
