jtreg version 4.1 splits command-line arguments by spaces despite they are in quotes.

Please, see next code of Test.java

/*
 * @test
 *
 * @run main Test "Argument with spaces"
 */
 
 public class Test
 {
     public static void main(String... args)
{
            throw new RuntimeException("Args length " + args.length);
}
 }

If I run this program stand-alone like:

java Test "Argument with spaces"

Log will be
Exception in thread "main" java.lang.RuntimeException: Args length 1
That is expected behavior because arguments in quotes recognized by java as one argument.

If I run the same test with jtreg it will be
Execution failed: `main' threw exception: java.lang.RuntimeException: Args length 3

Seems like in this case quotes are ignored and argument is split by spaces.
