Hi Daniil,
Overall it looks good. 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

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. Probably
at least for some tests
it makes to filter out some properties (e.g. -Xcomp) before forwarding them to
j*-tools.
