Initialize VM arguments to the static variable

Question

I am working on the JUL - Log4j 1.x bridge. I was follow this steps https://stackoverflow.com/a/4318607. Everything work fine, when I using VM argument:

-Djava.util.logging.manager=org.apache.logging.julbridge.JULBridgeLogManager

But I can't using VM arguments, it is some way how to set this classpath like static variable? For in exmple in Main.class

Or somehow set java.util.logging.manager (LogManager class) to JULBridgeLogManager

You can set system properties with `System.setProperty` **but** it varies a lot *when* those properties are read. I don't know if that specific property will be read/interpreted before execution reaches your main class. If it is, then setting it won't have any observable effect. — Joachim Sauer, Mar 23 '22 at 10:25
@JoachimSauer I will try, but when I want set my logging manager it will be System.setProperty("java.util.logging.manager", "org.apache.logging.julbridge.JULBridgeLogManager"); Or I must somehowe create property? — Sepi, Mar 23 '22 at 10:54
Yes, that would be it. There's no distinction between setting and creating. — Joachim Sauer, Mar 23 '22 at 10:57
then the property is apparently read before your code is reached. Seems you need to figure out how to set the system property from the command line after all. — Joachim Sauer, Mar 23 '22 at 11:20
@JoachimSauer it is solved. I did put System.setProperty(...) to the static block and worked well. Thank you for your advice. — Sepi, Mar 23 '22 at 12:41

I used in Main class static block and delete VM arguments and that worked well:

static {
    System.setProperty("java.util.logging.manager", "org.apache.logging.julbridge.JULBridgeLogManager");
}
