Access restriction: The type ResolverConfiguration.Options is not accessible due to restriction on required library C:\Program Files\Java\jre6\lib\rt.jar

This error may occurs when your project is not able to identify your JRE system library. So the get the workaround you have to follow these steps.


-->Go to the project properties.
-->Remove the JRE System Library
-->Add it back :
                     Select "Add Library" and select the JRE System Library.

The main reason for this to happen is that if  you are trying to replace a standard class which ships with some different Java Version with one in the library you have.
