I too was getting this. I believe this an issue with the JDK. Adding a server was working with JDK 1.6.0.11. When I upgrade to 1.6.0.12 I get this error. Switching the JDK back to 1.6.0.11 resolves the problem for me. For those who don't know... To change the JDK that netbeans uses, change the 'netbeans_jdkhome=' setting in this file C:\Program Files\NetBeans 6.5\etc\netbeans.conf.
