    Default Do services ever use cached copies of Jars?

    Suppose there is a service running off a jar, Example.jar. Suppose that while it was running, it was renamed to Example2.jar. Would this always disrupt the service, or would a service be running off a cached copy of the jar?

    I am assuming that there is nothing in the code that deliberately creates a cached copy of the jar.

    Please explain what OS and what service you are asking about.
    How does this question relate to java programming?
    If you don't understand my response, don't ignore it, ask a question.

    You can't rename an open file in Windows you have to disconnect the file handle so yes it will fail. I am fairly certain in Linux based OS you can rename the open file but it should have no effect unless your code calls that file by name specifically which in that case it will definitely fail to open. You should write a simple loop to test it.
