Java environment on Raspberry Pi

I have a Raspberry Pi 3 and have a Java application that I want to call from command line. All works fine, except that I have to wait about 15 seconds for the Java virtual machine to start up before my application is being executed. Is there a way to keep the JVM up and running all the time and let it know that it shall process my application from time to time?

hello, your post is missing some additional information (commands issued, distro and softweare versions etc), but i think i get the gist.

is this some sort of server?

why can't you just keep the application running? start it once (as a service maybe, or manually) and just keep it running?

i also use a java application on my server (libresonic) and it takes minutes to come up, but once it's running i don't need to exit it anymore (and it doesn't take too many resources).
