It is not possible to profile simle java application on JDK 9. To reproduce:

- run IDE with secret option -J-Dorg.netbeans.profiler.separateConsole=true
- create new java project
- add some code to main class, e.g.

    public static void main(String[] args) {
        for (int i = 0; i < 10000; i++) {
    public static void m1() {
        for (int i = 0; i < 100000; i++) {
            double d = Math.cos(Math.random());
            System.out.println("d=" + d);

- right-click project node and choose Profile
- select Methods
- click Profile but it ends with EXCEPTION_ACCESS_VIOLATION
