robaho / httpserver Goto Github PK

I'd be keen to have a play. I have a "routing layer" that I can put on top of it. I also have source code generation for controllers to the "routing layer" for Helidon 4, Javalin, Grizzly and the JDK http server.

Ref: https://github.com/avaje/avaje-http for the controller api (e.g. @Get, @Post etc) and annotation processors that target Helidon 4 etc

When I start my server and the System.Logger LOG4J bridge (org.apache.logging.log4j:log4j-jpl:2.22.1) is loaded, I get the following NPE:

java.lang.NullPointerException: Cannot invoke "java.util.logging.Logger.setFilter(java.util.logging.Filter)" because the return value of "java.util.logging.LogManager.getLogger(String)" is null

When I remove all traces of the logging provider, it works.

The problem seems to be that LogManager.getLogger returns a null pointer because the Logger isn't known yet.
It might be better to use Logger.getLogger instead, because that method creates a named Logger if it does not exist yet.
