Enabling Java assertions not working with Eclipse Luna

I tried enabling assertions for Java 8 in Eclipse Luna by doing what most answers on here suggest, adding -ea as a VM argument in the Run config, as well as in the default VM arguments in the JRE config. Still I get the same error as before:

Multiple markers at this line - 'assert' should not be used as an identifier, since it is a reserved keyword from source level 1.4 on - Syntax error on token "assert", ( expected - Syntax error, insert "AssignmentOperator Expression" to complete Expression - Syntax error, insert ")" to complete Expression

My program is really just a simple program to try it out:

public class Test {

    public static void main (String[] args) {
        int x = 10;
        assert x != 0 : "Test";
        System.out.println(x);
    }

}

What am I doing wrong?

I thought I anwer my own question, since the solution was hidden in a comment until now:

Removing -ea from the default parameters, but keeping it in the run configuration solved the problem, for me.

Go to Window -> Preferences -> Java -> Installed JREs -> select your installed JVM -> Edit.. -> in "Default VM arguments:" add -ea.

Finally make sure that your project uses same JVM in which you added -ea as default argument. To do that :

right click on project -> Properties -> JavaBuildPath -> Libraries here you should see JRE system library[...]. Make sure that in [...] is JVM you edited to enable assertions.

Keep parentheses around the x != 0. That might fix your problem.
