Hi all,

could you please review the trivial patch which updates 109 runtime tests to use driver mode?

in most cases, the changes are as straightforward as 's/main/driver/', other changes are:
 - runtime/InvocationTests tests throw an exception instead of calling System.exit
 - runtime/condy/CondyLDCTest.java passes "-Xverify:all", although the test didn't do that before, it seems it was intended, in any case it won't cause any harm
 - in runtime/records/ignoreRecordAttribute.java, indent of jtreg test description block was fixed.

(for the sake of reviewers, copyright year changes are omitted, the final patch changes years in )
JBS: https://bugs.openjdk.java.net/browse/JDK-8243945
testing: test/hotspot/jtreg/runtime

Thanks,
-- Igor
