Open SSL not available because of java.lang.ClassNotFoundException: org.apache.tomcat.jni.SSL

SG2.4.1

JVM1.8

I put netty-tcnative-boringssl-static-2.0.11.Final.jar in searchguard-ssl folder ,it still report this warning:

Open SSL not available (this is not an error, we simply fallback to built-in JDK SSL) because of java.lang.ClassNotFoundException: org.apache.tomcat.jni.SSL

Pls help.
