+# In JDK 24+ any attempts to enable the security manager will result in an error
 # In JDK18+, java.security.manager == null behaves as -Djava.security.manager=disallow.
 # In JDK17-, java.security.manager == null behaves as -Djava.security.manager=allow.
 # In case of system tests, the base infra (STF) which is used to launch tests utilizes
 # the security manager in net.adoptopenjdk.loadTest.LoadTest.overrideSecurityManager.
 # For system tests to work as expected, -Djava.security.manager=allow behaviour is
 # needed in JDK18+.
