I'm currently trying to build an app with log4j/slf4j and java 11 but I'm facing this problem at runtime:
2018-12-10 22:09:27,225 main INFO Cannot initialize scripting support because this JRE does not support it. java.lang.NoClassDefFoundError: javax/script/ScriptEngineManager

The code that is at the origin of this is the initialization of my logger:
private static final Logger LOGGER = LoggerFactory.getLogger(NameAsCreated.class);
I have dependencies on:
- org.apache.logging.log4j:log4j-api:2.11.1
- org.apache.logging.log4j:log4j-core:2.11.1
- org.apache.logging.log4j:log4j-slf4j18-impl:2.11.1
- A maven project that depends on org.slf4j:slf4j-api:1.8.0-beta2
I'm on OSX Mojave with Java version:
openjdk version "11" 2018-09-25
OpenJDK Runtime Environment AdoptOpenJDK (build 11+28-201810021910)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11+28-201810021910, mixed mode)
Does someone have an idea of what I'm doing wrong and how I can solve this?

According to the Log4j documentation:
Log4j provides support for JSR 223 scripting languages to be used in some of its components.
and as said in the comments by Alan Bateman from Java 9 you have to add explicitly the java scripting module either with --add-modules java.scripting or in module-info.java.
Note also that the module jdk.scripting.nashorn is deprecated in Java 11 and will be removed in a future release.
