Fix for https://bugs.openjdk.java.net/browse/JDK-8022211

[Tristan Yan]

Hi Everyone   I have a fix for https://bugs.openjdk.java.net/browse/JDK-8022211, could you review it. Since we have Kurchi's code change out for review for re-writing this test to use the new HTTP Server API. We have 2 option here  1. Just fixing the bug with move setCondition around.  2. Adopting Kurchi's code change and my fix together as a whole fix.  I propose we're using second way, the reason is Kruchi was using modern API of JDK, it's less error-prone and make test shorter, I'd like to shameless steal her fix as part of my fix.    http://cr.openjdk.java.net/~pzhang/Tristan/8017779/webrev/   Tristan Yan(Haibo Yan) Office : 8610-61066212 Fax  : 8610-61065441 Cell  : 86-18610696822   2F, Building No. 24, Zhongguancun Software Park Haidian District Beijing , 100193
