Dyanamic class load for server side application

Is there a problem to use reflection (specifically class.forName) in server side application? My main thread about this is someone to inject a code dumping memory in JVM and adding commands in reference memory field, but this is unlike in server side (and if server side was compromised this will be a minor problem). Btw, I am asking because static analises keep acusing as a vulnerabiliy
