Wrong toString() generation when there are promitive arrays as fields

[GoogleCodeExporter]

>> What steps will reproduce the problem?

1. Create a class:
public class Vector {
    private double[] values;
}

2. Alt+Ins, then toString(), then we see

>> What is the expected output? 

Something like this, which works:

public class Vector {
    private double[] values;

    @Override
    public String toString() {
        return "Vector{" +
                "values=" + (values == null ? null :
Arrays.toString(values)) + '}';
    }
}

>> What do you see instead?

import java.util.Arrays;

public class Vector {
    private double[] values;

    @Override
    public String toString() {
        return "Vector{" +
                "values=" + (values == null ? null : Arrays.asList(values))
+ '}';
    }
}

which is wrong because Arrays.asList does not work as expected on primitive
arrays (it is a vararg method).

>> What version of the product are you using? On what operating system?

The one that is shipped with IntelliJ IDEA 8.1. Linux.

Please provide any additional information below.

Suppose to replace Arrays.asList with Arrays.toString. It doesn't create a
list object and correctly works with nulls.

Sorry for mistakes,
promitive -> primitive
suppose -> suggest

Good idea, I think changing the template provided out of the box is all what is 
needed.
