Prior to this commit, our BlockHound integration tests were disabled
after the migration to a JDK 17 baseline since the build now always
runs on JDK 14 or higher.
To re-enable the tests we now supply the deprecated
-XX:+AllowRedefinitionToAddDeleteMethods command-line argument to the JVM
for tests in the Gradle build. Users can also configure this manually
within an IDE to run SpringCoreBlockHoundIntegrationTests.
If that command-line argument is removed from the JVM at some point in
the future, we will need to investigate an alternative solution.
See https://github.com/reactor/BlockHound/issues/33 for details.
