Java compilation error: cannot find symbol

I have a code that is successfully compiled in Idea but fails to be compiled by maven clean package. The code is

import java.util.concurrent.*;

public class WebStatusMonitor {

    private ConcurrentMap<String, Double> load = new ConcurrentHashMap<>();

    public void handle(...) {
        ...
        snapshot.add(String.format("cpu: %s", load.getOrDefault("cpu", 0.)));
        ...
    }

And compilation fails with error

[ERROR] WebStatusMonitor.java:[121,66] cannot find symbol
symbol:   method getOrDefault(java.lang.String,java.lang.Double)
location: variable load of type java.util.concurrent.ConcurrentHashMap<java.lang.String,java.lang.Double>

I have included what I use (actually everything was included automatically by Idea) and this code is even compiled successfully in Idea. Am I missing something?

It looks like your IDE uses java 8 and your maven is configured to use java 7.

The method does not exist in java 7 and does exist in java 8
