BeautyEye的透明效果为何不支持Java1.6_u10和u11

原因如下

Java虽是从Java1.6_u10版（曾今被SUN寄于厚望的版本）支持透明窗体API，但BeautyEye至少需要Java1.6_u12及以上版本才可支持透明效果。原在在于：Java1.6_u10里存在一个bug（BUG ID：6750920），而此bug直到Java1.6_u12才被修复（参见SUN官方的Java版本更新说明：Realease note）。明白了吧。

关于Bug: 6750920

引用：Java官方BUG ID：6750920，查看地址：http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6750920。

此BUG将使BueatyEye L&F(或其它使用透明API的程序)运行时产生异常而中断运行：

很好，终于知道原因了！
