We compile and test Apache Nutch on Solaris with the Java 7 (latest) JDK and all is good. I run Apache Nutch on some CI ubuntu servers. I do not run on Windows. This may be a problem, or it could be your development environment, or it could be something else. I have not engaged in this conversation before, so I can only assume it is something to do with your local environment.
