Hi Chris, Please review a new version of webrev [1] that addresses your comments.
For the following 3 tests that showed the increase of the execution time with -Xcomp more than 5 minutes this version of the change strips -Xcomp option when forwarding VM arguments to j*-tools : -- serviceability/sa/sadebugd/SADebugDTest.java, -- serviceability/sa/sadebugd/DebugdConnectTest.java, -- serviceability/sa/ClhsdbJstackXcompStress.java The execution time for the rest of the tests when running with -Xcomp was increased within 1 and half minute.

A few comments below. Can you add a comment to TestSysProps.java indicating the reason for checking if the line starts with "[". In JDKToolLauncher you have an extra empty line: 112 * Any platform specific arguments required for running the tool are 113 * automatically added. 114 * 115 * 116 * @param args In OutputAnalyzer.java, I wonder if all these matching APIs you updated should by default just include the version output in their filtering. As for the added time to execute, I would suggest possibly stripping -Xcomp from the few outliers, and I would mostly focus on how much longer it takes, not how many times longer. For example, increasing from 10 seconds to 40 seconds is not a big deal. Increasing from 10 minutes to 20 minutes is. SADebugDTest creates 8 tool processes so, that's probably the reason for the big increase, although I'm not sure why it is kind of slow in the first place. It does nothing more on each iteration than launch "jhsdb debugd", which will connect to the debuggee, and then is killed off. Maybe there is something slow with connecting, especial with RMI. thanks, Chris On 4/27/20 12:07 PM, Daniil Titov wrote: > Please review the change [1] that ensures that VM and test options are forwarded to > j*-tools when they are launched from serviceability/sa tests. > > The tests that expect an empty output were corrected to ignore the product version printed > in the error stream since in some tiers the tests are run with ' -showversion' VM option (tier3). > > In test serviceability/sa/TestSysProps.java the code that counts the system properties was corrected > to ignore the debug output when the test is run with " -Xlog:cds=debug" option (tier4). > > Testing: Mach5 tests for tier1 - tier7 passed. > > I also run the test with -XComp at Mach5 linux-x64-debug builds before and after the changes > and for the most of the tests the overhead is about 2 times although for > serviceability/sa/sadebugd/SADebugDTest.java it spikes up to 5 times.
