JVM Core dumps on 8-jre-alpine docker image

[santhoshsath]

I have an existing lightbend Play server in production running as a docker image
recently I added a pulsar client library to it (org.apache.pulsar:pulsar-client:2.7.2)
I tested the connectivity on my laptop and everything runs well
After testing, I created a docker image of my server
When I run it in docker, the JVM core dumps when I try to create the client instance
PulsarClient.builder().
serviceUrl(serviceUrl).
allowTlsInsecureConnection(false).
tlsTrustCertsFilePath(tlsTrustCertsFile.getAbsolutePath).
authentication(authClassName, authParams.asJava).
connectionTimeout(connectionTimeout,TimeUnit.MILLISECONDS).
build()
Attached is the java core dump file
hs_err_pid1.log

At the very least is there a way to disable epoll and use java nio in pulsar client ?

I had to upgrade to 2.7.2 because the lower versions had security vulnerabilities as reported by blackduck.
It's that .so file packaged with 2.7.2 jar, I think it was a mistake to package a buggy .so

pulsar-client-2.7.2.jar/META-INF/native/liborg_apache_pulsar_shade_netty_transport_native_epoll_x86_64.so

If I remove that .so from the jar file, and rebuild the docker image it runs fine

If one wants to use an alpine base image, eclipse-temurin:17-alpine base image can be used. Eclipse Temurin images are maintained by Adoptium. Adoptium provides pre-built OpenJDK binaries.
