Only changeset associated to this build corresponds to https://bugs.openjdk.java.net/browse/JDK-8153027: "Exclude tools/jimage/JImageTest.java" which seems to have nothing to do with this intermittent networking test issue.

The following change set was intended to increase stability of the test, we need to inspect it (JDK-8151582).

Root cause: for JDK-8068693, 500ms is too short on busy system for channel to be closed or for thread blocking on IO to be interrupted. for JDK-8153209, it's a test regression due to JDK-8151582 (http://hg.openjdk.java.net/jdk9/jdk9/jdk/rev/88577677aec9). There is a time window between thread ready and io operation ready, deleting the original sleep(100) might cause channel closed before accessing the channel. Suggested Fix: for JDK-8068693, increase the time from 500ms to 10000ms. for JDK-8153209, do not sleep when running tests for CONNECT/FINISH_CONNECT, sleep for other test cases.

[~ggalimbe] Thanks for tracking the issue. 1. The issue reported here in this bug is tracked by JDK-8068693, I think they are duplicated. Could I suggest mark this bug as duplicate of JDK-8068693 and close it? 2. The issue fixed by JDK-8151582 is a different issue, it's a high frequent test issue.

Hamlin, pls investigate the associated changeset, we might still have some error windows.
