Any attempt to use <junitreport> (in the default "frames" mode) inside the IDE
running JDK 7 fails:

Errors while applying transformations:
javax.xml.transform.TransformerException: java.lang.RuntimeException: Use of
the extension element 'redirect' is not allowed when the secure processing
feature is set to true.

The same works outside the IDE using JDK 7, or inside the IDE using JDK 6.

=============================================================

This error still present and is a real issue, the problem occurs when use ANT
1.8.2(Netbeans's default lib) and JDK7 and you try to transform the XML file
using Ant file.
Expected Result: The must recently ANT lib should be contained in Netbeans.
Work Around: use apache-ant-1.8.3 with JDK-7 or use apache-ant-1.8.2 with JDK-6

==============================================================

 如果现在使用的Eclipse的Ant版本低于1.8.3，那么可以手动更新Eclipse中的Ant版本，更新办法见http://zorro.blog.51cto.com/2139862/839046
