In response to: Groovy - Could not create SecurityManager
Comment from: Ujjwal [Visitor]

I want to thank you for this post - it saved me a lot of time and trouble.
I was surprised why a Homebrew package would be so broken, so I did some digging about the root cause… I can’t say what the root cause is for you, but for me it’s because I had $JAVA_HOME set to a Java 11 implementation. Support for -Djava.security.SecurityManager=allow
seems to have been added in Java 12. Search for “allow” (including quote marks) [here](https://docs.oracle.com/en/java/javase/12/docs/api/java.base/java/lang/SecurityManager.html) vs [here](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/SecurityManager.html)
$controller = Yii::$app->controller; $default_controller = Yii::$app->defaultRoute; $isHome = (($controller->id.'/'.$controller->action->id === $default_controller) && ($controller->action->id === $controller->defaultAction)) ? true : false;
HI. Please help me. when I run red5.sh, I get to see the following
