RFR(S): 6755586: Test com/sun/jdi/NoLaunchOptionTest.java may erroneously fail

[Yekaterina Kantserova]

Hi,

Could I please have a review of this small fix.

bug: https://bugs.openjdk.java.net/browse/JDK-6755586
webrev: http://cr.openjdk.java.net/~ykantser/6755586/webrev.00/

This bug is actually already solved. But I'll use it as an opportunity 
to re-write the test using test library. There is no need to retrieve a 
free port since the error occurs before binding to the address.

Thanks,
Katja
