Cannot find package java.nio.file

Question

My java compiler cannot find the java.nio.file package. Consider:

import java.nio.file.*;
public class Test {
    public static void main(String[] args) { 
        Path currentRelativePath = Paths.get("");
    }
}

compiling with

bash$ javac Test.java

gives

Test.java:1: package java.nio.file does not exist
import java.nio.file.*;
                ^
Test.java:5: cannot find symbol
symbol  : class Path
location: class Test
    Path currentRelativePath = Paths.get("");
    ^
Test.java:5: cannot find symbol
symbol  : variable Paths
location: class Test
    Path currentRelativePath = Paths.get("");
                               ^

I am using Ubuntu 12.04, and I think I have JDK 7 installed (see: package java.nio.file does not exist )

bash$ java -version
java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.12.04.2)
OpenJDK 64-Bit Server VM (build 23.7-b01, mixed mode)

It is entirely possible that you have java 1.7, but javac 1.6 or even 1.5

maybe you can use

sudo update-alternatives --config javac

to configure it. If you cannot choose 1.7, then you need to upgrade your JDK package.
