The root cause of the failure in https://bugs.openjdk.org/browse/JDK-8353433 was written by @coffeys in the bug. Right now It needs a test case to verify when future cut-over time is passing and the currency is going to work properly. Here is the example defined in CurrencyData.properties, "CW=ANG;2026-04-01-04-00-00;XCG".  Technically it needs to overwrite the return value of System.currentTimeMillis() and make it return with future time to trigger the test for future currency.

see this line https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/java/util/Currency.java#L423.

BTW, @justin-curtis-lu made the change in the mainline of JDK at https://bugs.openjdk.org/browse/JDK-8354344. Since it is using ClassFiie API, it can not be backported to jdk with version 23 or lower.
