Upgrade the JUnit dependency to the latest available 5.4.0.
Note that JUnit simplified its artifacts, and now it contains a
single, simple org.junit:junit-jupiter artifact.
This patch finalizes the upgrade of commons-lang's tests to use JUnit
Jupiter and remove the Vintage Engine dependency entirely.
While most of these changes are drop-in replacements with no functional
benefit, there are some non-obvious changes worth mentioning.
Unlike org.junit.Assert.assertEquals(double, double, double),
org.junit.jupiter.api.Assertions.assertEquals(double, double, double)
does not support deltas of zero, only strictly positive deltas.
This issue will be addressed in JUnit Jupiter 5.4 (see
https://github.com/junit-team/junit5/pull/1613 for details). In the
meanwhile, assertTrue(expected==actual) was used, and TODO comments were
placed in the code to refactor it to assertEquals once JUnit 5.4 is
available.
Unlike org.junit.Test, org.junit.jupiter.api.Test does not have an
"expected" argument. Instead, an explicit call to
org.junit.jupiter.api.Assertions.assertThrows is used.
Unlike org.junit.Test, org.junit.jupiter.api.Test does not have a
"timeout" argument either. Instead, an explicit call to
org.junit.jupiter.api.Assertions.assertTimeoutPreemptively is used.
JUnit Jupiter also no longer has the concept of Rules. Usages of the
SystemDefaultsSwitch rule and its accompanying annotates were replaced
with the @DefaultLocale annotation that Benedikt Ritter contributed to
JUnit Pioneer, the semi-official JUnit extension project.
Following the removal of their usages, the SystemDefaults annotation,
the SystemDefaultsSwitch rule and the SystemDefaultsSwitchTest class
that tests them had no more use, and they were removed entirely.
It's also worth noting this is a minimal patch for migrating the
package's tests to Jupiter. There are several tests that can be made
more elegant with Jupiter's new features, but that work is left for
subsequent patches.
Upgrade the tests in the time package to use JUnit Jupiter as
part of the effort to remove the dependency on the Vintage Engine.

JUnit Jupiter no longer has a concept of runners. Tests previously run
with the org.junit.runners.Parameterized runner were rewritten to use
@ParameterizedTest and a @MethodSource.
