java - To use javac bootclasspath do i need everything in jre/lib or just rt.jar? -


when trying compile targeting java 5 java 7 , set bootclasspath parameters examples see need rt.jar jre/lib directory. don't see errors @ , seems work, sure, having folder rt.jar inside enough? or need complete lib folder?
