Please, review the following test change Issue : https://bugs.openjdk.java.net/browse/JDK-8077402 Webrev: http://cr.openjdk.java.net/~jbachorik/8077402/webrev.00
Currently, the test waits for 5*{timeout.factor} seconds for the target application to start up before timing out. On extremely slow machines even the timeout.factor will not assure a successful target application startup and the test will fail sporadically.
The proposed solution is to defer timing-out to the test harness. The test library will still take care of collecting the thread dump and terminating any left-over processes (ProcessTools.startProcess() methods). While this will not remedy the failures on extremely slow machines it is better not to introduce any additional arbitrary time-out limits.
As a part of this patch there is a small clarification in the javadoc of ProcessTools.startProcess() method and a null check in JMXStartStopTest$TestAppRun to prevent NPE hiding the timeout message.
Thanks, -JB-
