Trying to create check point in spring boot application but failing with the below error
jdk.crac.impl.CheckpointOpenSocketException: tcp6 localAddr :: localPort 8088 remoteAddr :: remotePort 0 at java.base/jdk.crac.Core.translateJVMExceptions(Core.java:88) at java.base/jdk.crac.Core.checkpointRestore1(Core.java:142) at java.base/jdk.crac.Core.checkpointRestore(Core.java:237) at java.base/jdk.crac.Core.lambda$checkpointRestoreInternal$3(Core.java:259) at java.base/java.lang.Thread.run(Thread.java:833)
I used the spring.context.checkpoint=onRefresh in application.yml file.
Implemented beforeCheckpoint method and close the connection opened by application. However spring web server is not being closed and throwing exception.
jdk : openjdk-17-crac+3_linux-x64 springBootVersion = "3.3.0"
Appreciate any pointer and solution on this
Comment From: sdeleuze
spring.context.checkpoint=onRefresh is not a Spring Boot property you should set in application.yml but a JVM system property as documented here. I suggest you fix your use case accordingly by using java -Dspring.context.exit=onRefresh ..., you should not have to implement beforeCheckpoint to close the connection opened by the application. https://github.com/spring-projects/spring-lifecycle-smoke-tests/ provides addition guidance for database etc.
