Although no Clhsdb test is explicitly always runs with `-Xcheck:jni`, the
option can be added to any test run. For example:
`$ make test TEST=open/test/hotspot/jtreg/serviceability/sa/
TEST_VM_OPTS="-Xcheck:jni"`
This matching is done to make sure there are no warnings when the test is run
in this manner. The matching could be conditional on the test being run with
`-Xcheck:jni`, but I don't really see to point in cluttering up the logic with
such a check since the warnings should never appear, whether or not you are
using `-Xcheck:jni`.
