Hi Xuelei,
I am not sure why you think it's too strong to follow to it. To me it's pretty
easy to see if a test calls System.setProperty() or Security.setProperty()
methods which modify default JSSE configuration.
Is there any other way to modify default JSSE configuration, so that it can't
be changes then?
Yes.
Could you give an example?
And even it can only be set via explicit call to setProperty(), run it in agent
vm is still not safe because we don't know where the set may be used other than
this test case.
Those tests which modify default JSSE configuration should be run in
othervm mode. This way they won't affect any other tests.
It is not only about this test, the impact need to consider all JDK test
cases in a big picture, which is a huge number and we cannot actually evaluate
so many test cases.
I think we just need to identify all tests that modify default JSSE
configuration, and make them run in othervm mode. I believe that
currently most of them run in othervm mode.

I will reply more details when I have a PC tomorrow.

I think Artem is correct here.
All those tests that modify static fields should run in othervm mode, so
that *each* runs in its *own* VM. All other tests, which make no such
modifications, can share the *same* VM using agentvm.
It's too strong to follow. And it is not easy to know there is no static
fields update in a test case.

Those tests which modify default JSSE parameters should be run in

agent VM. This test doesn't seem to modify any default JSSE parameter.
If this test get booted, other test that need to do more customization
may not work any more.
For example, boolean variable A is a singleton static field, default is
true. If A get initialized in default mode, it is "true". It is not
possible to customize it to "false" any more in other test in
agentvm/samevm mode.
Shouldn't these "other" tests run in othervm mode?
Or, do you mean that even if a JSSE test does not modify a static field
inside the test, it will modify some through innocent JSSE calls, so no
JSSE test should ever run in agentvm?
I find this unnatural.
Thanks

This test has no impact in agentvm/samevm mode unless no test run in
agentvm/samevm mode or all tests run in agentvm/samevm mode has the same
configuration as this one. This assumption is too strong to follow.
