> When running {{groovysh}} on JDK18 and above, the use of the security manager
> to prohibit calling System.exit() needs to be explicitly enabled by setting
> {{java.security.manager}} to {{allow}}.
> Previously, when setting that property, {{groovysh}} runs (with an expected
> WARNING) and guards against attempts to call System.exit(). This behavior is
> unchanged by this issue.
> Previously, when that property is not set, {{groovysh}} won't start and
> instead fails with an UnsupportedOperationException. This issue changes the
> behavior when the property is not set to not attempt to use the
> NoExitSecurityManager. Instead, {{groovysh}} starts but attempts to call
> System.exit() cause {{groovysh}} to immediately exit.
