Thirsty? Want Some Java?
On a few of the forums people have stated that Google has been following some Java links with a new spider by the name of "Googlebot/Test." There is an ongoing post at WebmasterWorld and Shawn of Digital Point also posted a detailed post about it.

Affiliate marketers and others using Java to cloak links will soon need to use redirects and a robots.txt file in place of the Java to keep Google from spidering your cloaked links.
