moneta-concurrent-init

This repo is a minimal reproducible example for a following StackOverflow answer: https://stackoverflow.com/a/61715268/3456163

Run

Java 11

A version without concurrent init (completed successfully):

docker run -it --rm iakunin/moneta-concurrent-init:java11

A version with concurrent init (No MonetaryAmountsSingletonSpi loaded error):

docker run -it --rm --env SPRING_PROFILES_ACTIVE=race-condition iakunin/moneta-concurrent-init:java11

Important note: It may take several runs to reproduce the error. Just try again if there is no error. However, there could be no error on single-core environment or environment that does not support parallel computations.

Make sure of docker-image really contains Java 11:

docker run -it --entrypoint '' iakunin/moneta-concurrent-init:java11  java -version

Java 8

A version without concurrent init (completed successfully):

docker run -it --rm iakunin/moneta-concurrent-init:java8

A version with concurrent init (also completed successfully):

docker run -it --rm --env SPRING_PROFILES_ACTIVE=race-condition iakunin/moneta-concurrent-init:java8

Make sure of docker-image really contains Java 8:

docker run -it --entrypoint '' iakunin/moneta-concurrent-init:java8  java -version

Build

To build a jar from sources use following command (you must have docker installed):

bash bin/gradle_in_docker.sh clean build

Then you can run just built jar:

java -jar  build/libs/moneta-concurrent-init.jar

Or:

java -jar -Dspring.profiles.active=race-condition build/libs/moneta-concurrent-init.jar
