SLF4J Issue in transformer context

[odoodo]

Environment

• Microsoft Windows Server 2022 Standard
• Mirth v4.5.0
• Java 17

Context
Log4J2 supports SLF4J. This allows to write logging statements similar to the Java String.format() function and allows things like:

var testValue = 'Test';
logger.info('This is a {} of SLF4J', testValue);

which would result into
This is a Test of SLF4J

Issue
This works flawlessly in the Mirth JavaScript context like deploy, connector, or filter scripts.

However, in the Mirth transformer context it throws the following error:
Can't find method org.apache.log4j.Category.info(string,string). at d9bf574e-ad4b-4462-9923-87163a07c995_JavaScript_Filter_Transformer_4:5051 (doTransform) at d9bf574e-ad4b-4462-9923-87163a07c995_JavaScript_Filter_Transformer_4:5452 (doScript) at d9bf574e-ad4b-4462-9923-87163a07c995_JavaScript_Filter_Transformer_4:5454 at com.mirth.connect.server.transformers.JavaScriptFilterTransformer$FilterTransformerTask.doCall(JavaScriptFilterTransformer.java:235) at com.mirth.connect.server.transformers.JavaScriptFilterTransformer$FilterTransformerTask.doCall(JavaScriptFilterTransformer.java:187) at com.mirth.connect.server.util.javascript.JavaScriptTask.call(JavaScriptTask.java:114) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.lang.Thread.run(Thread.java:842)

This seems quite strange to me, especially as it is working w/i filter scripts that run in the same context.
It very, very likely also affects all Mirth forks so far.

Is this a know issue (I did not find anything) or has anyone a clue what happens there?
