Java: Cannot find symbol: variable Objects

I generated methods hashCode() and equals(Object obj) by netbeans insercode. In netbeans I can compile without errors, but when I compile it on my server with javac: ``` bangserver/Login.java:3: cannot find symbol symbol : class Objects location: package java.util import java.util.Objects; ^ ``` and other errors with Objects... ``` public int hashCode() { int hash = 5; hash = 47 * hash + Objects.hashCode(this.password); return hash; } ``` What you guys think should be problem he can't find java.util.Objects ?
