I have probably removed some classes that I shouldn't have removed, because when I'm making a project in eclipse, everything works fine when I set my project to use java SE 1.5, but when I try to use version 1.6, it says the type 'java.lang.object' cannot be resolved. rerunning the java installation package doesn't wrk, how can I fix this?
