RFR(T) : 8243945 : use driver mode in runtime tests

[Igor Ignatyev]

Dan, Gerard,

I've added -XX:+EnableThreadSMRStatistics in both NestedThreadsListHandleInErrorHandlingTest and ThreadsListHandleInErrorHandlingTest, and -Xverify:all in CondyNewInvokeSpecialTest: http://cr.openjdk.java.net/~iignatyev//8243945/webrev.0-1/

the tests are still passing.

>>> How did you determine which tests need to be updated to use driver mode? Can there be more?
>> this clean (as well as a few other) is a side effect of me working on JDK-8151707 where I used instrumented build of JDK to find tests which don't pass JVM flags to child processes, as I was mostly interested in a subset of all tests which fork processes, there can be other which can/should use driver mode.
>>> In "ProtectionDomainCacheTest" we used to have extra arguments, i.e. "policy=test.policy -Djava.security.manager ProtectionDomainCacheTest", but now we don't?
>> right, ProtectionDomainCacheTest itself didn't need security manager being setup, it's needed for JVM which runs ProtectionDomainCacheTest$Test and L#99 and L#105 add these flags.

>>> In "NestedThreadsListHandleInErrorHandlingTest" we used to have "-XX:+UnlockDiagnosticVMOptions -XX:+EnableThreadSMRStatistics", but now we don't?

>>> In "ThreadsListHandleInErrorHandlingTest" we used to have "-XX:+UnlockDiagnosticVMOptions -XX:+EnableThreadSMRStatistics", but now we don't?
>> in both cases, we didn't have these flags in JVM which was doing actual testing, and I doubt EnableThreadSMRStatistics from the JVM which just creates a process and waits for it to finish is helpful. I can add -XX:+EnableThreadSMRStatistics to the child JVM if you think it can be helpful.
