@karol.wojcik is it possible to invoke a lambda from the command line? 

java  -jar .holy-lambda/build/output.jar "example.core.MyLambda" 
WARNING: abs already refers to: #'clojure.core/abs in namespace: cljc.java-time.duration, being replaced by: #'cljc.java-time.duration/abs
Exception in thread "main" java.lang.NullPointerException: Cannot invoke "String.toString()" because "runtime" is null

Presumably, I need to get a payload to the function? Do you happen to know what format that might take?

I should clarify that I know I can use sam invoke for interacting with my lambda. My goal here is to run the app as part of a docker build to capture shared class data: 

RUN java -XX:ArchiveClassesAtExit=classes.jsa -jar output.jar "example.core.MyLambda"

CMD java -XX:SharedArchiveFile=classes.jsa -jar output.jar "example.core.MyLambda"

I figured it out. Will detail my method later if anyone’s interested

As I remember there is executor JVM property I’m using to gather reflective calls.
