[jdk17u] RFR: 8280890: Cannot use '-Djava.system.class.loader' with class loader in signed JAR

[Severin Gehwolf]

Clean backport fixing a regression introduced with [JDK-8269039: Disable SHA-1 Signed JARs](https://bugs.openjdk.org/browse/JDK-8269039) which was included in 17.0.5. This should be low-risk as it mainly removes use of `java.util.Calendar` API usage in `DisabledAlgorithmConstraints` which can cause issues with applications that contain `CalendarDataProvider`s in signed jars. See [JDK-8297684](https://bugs.openjdk.org/browse/JDK-8297684) for details.
