I m using a plugin for eclipse.
It has many bugs and crashes all the time.
Definitely the worst development tool of rules that have worked.
Make sure you are using a combination of Eclipse and Blaze Advisor that is supported (check the documentation). Also make sure the platform and Java version you are using are supported.
If you still experience bugs, please report them at http://www.fico.com/en/Services/Support/Pages/default.aspx
