embedded-elasticsearch fails in Concourse CI/CD

[kgrygoryan-clgx]

Hi, I have a Spring Boot app that uses your library for integration testing. It works fine on local machine, but it fails if app runs in Concourse-Ci.

gradle file

testCompile('pl.allegro.tech:embedded-elasticsearch:2.7.0')

java class

private final EmbeddedElastic embeddedElastic = EmbeddedElastic.builder()
            .withSetting(PopularProperties.CLUSTER_NAME, "my-application")
            .withElasticVersion("6.3.2")
            .withSetting(PopularProperties.HTTP_PORT, 21121)
            .withEsJavaOpts("-Xms128m -Xmx512m")
            .withStartTimeout(5, MINUTES)
            .build().start();

error from Concourse
