Issue description

I want to test CRaC image with Micronaut. My sample app use Micronaut Data and PostgreSQL database: https://github.com/alapierre/micronaut-sample. I'm trying to build image like that:

./mvnw package -Dpackaging=docker-crac -Dmaven.test.skip=true

but got error when checkpoint image starts:

INFO: Use -Djdk.crac.collect-fd-stacktraces=true to find the source.
STARTUPTIME 5887858889428 restore
STARTUPTIME 5887877052516 restore-finish
