Well, if you have to use that evil plugin [~Johnston], then at least configure 
it correctly.

Your problem has nothing to do with this bug, but that you leave out necessary 
files.

It is surely significant, that the plugins documentation even uses {{log4j}} as 
example for preventing the minimizing:

The issue is related to using the shade plugin to build my jar. If I don't set 
minimizeJar to true log4j is callable during runtime. If I don't set 
minimizeJar, the error is generated at runtime. I'm not sure what the intended 
functionality is to be. Here is my example:

 LOGGER.info("Here\n");
 }

Do you mean a nasty fat JAR when you say executable?

While "executable" actually is the wrong word, as the JAR is not really 
executed, or only means that the main class attribute is set in the manifest.

If you meant a fat JAR, did you maybe forget to package the services files from 
META-INF too?

If not, do you have an MCVE that you can provide?

I get a similar error (jdk 9.0.4) using log4j 2.11.0 during runtime of an 
executable jar. I extracted the jar and the classes are there, but java -jar 
MyClass.jar outputs:

Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize 
class org.apache.logging.log4j.util.PropertiesUtil

private static final Logger LOGGER = LogManager.getLogger(MyClass.class); // 37

Just in case someone needs a workaround because he cannot update, here is an 
easy one.
Compile a class named {{Log4JModulePatch}} that lies in package 
{{org.apache.logging.log4j}}.
Content of the class:
{code}
package org.apache.logging.log4j;

import org.apache.logging.log4j.message.ThreadDumpMessage.ThreadInfoFactory;
import org.apache.logging.log4j.util.PropertiesUtil;
import org.apache.logging.log4j.util.PropertySource;

public class Log4JModulePatch {
public static void patch() {
//TODO: Remove with log4j 2.11.0 or newer
Module log4jApiModule = PropertiesUtil.class.getModule();
log4jApiModule.addUses(PropertySource.class);
log4jApiModule.addUses(ThreadInfoFactory.class);
}
}
{code}
Package it as a JAR and use {{--patch-module 
org.apache.logging.log4j=path/to/log4j-api-patch.jar}} on execution.

You can also simple use the attached [^log4j-api-patch.jar] and use the 
{{--patch-module}} parameter mentioned above.

I've been also playing with jlink to create a self-contained image and I think

it work with just the uses for PropertySource?

Have you found any documentation on why the two "uses" declarations are 
necessary? All I could find is that uses is required to name the class used by 
the ServiceLoader. Not that there is anything wrong with your fix but I am 
wondering why it is needed.

One more addition: same code runs fine if executed with previous version of 
log4j2 and an auto-generated module name in module-info.java.
