Add-options double quoting

In case of add multiple options via <addOptions>, they are combined to one in runtime. For example :

<addOptions>
    <addOption>-Darg1=value1</addOption>
    <addOption>-Darg2=value2</addOption>
 </addOptions>

In runtime for the following code:

System.out.println(System.getProperty("arg1"));
 System.out.println(System.getProperty("arg2"));
 

Output is:

value1 -Darg2=value2
null

After I examined the source code, I noticed that in fact, in the final command, it turns out something like '"-Darg1 = value1 -Darg2 = value2"' instead of "-Darg1 = value1 -Darg2 = value2".

I.e double quoting.

My seggesion:

Remove reduntant quoting in file JlinkMojo(line:657).
