This test is not effectively testing standard ISO 4217 future transition
currencies. For example, with your patch, if I supply the following changes to
the ISO 4217 currency data:
(i.e. Make country `LK` have a transition currency of `XCH` in July)

With the above changes, we would expect this test to fail, since
`getInstance("XCH")` should throw an exception. However, your test still
passes. What this patch is doing is selectively testing a handful of Currencies
with the system property override. This is not sufficient to ensure test
coverage for testing a standard ISO 4217 transition currency after the
transition date has passed. As mentioned above, the system property override
does not mock a standard ISO 4217 transition currency, (they have different
functionality).
Also as @weibxiao has mentioned, we already have such a test in mainline.
Additional testing would be required as backports for LTS releases only.
