Spring Boot webapp with embedded vertx fails to start

问题

I am trying to start a Spring Boot webapp(executable war) with embedded clustered vertx. It fails with below exception.

java.lang.IllegalArgumentException: PortableFactory[-14] is already registered! com.hazelcast.concurrent.countdownlatch.client.CountDownLatchPortableHook$1@738ae532 -> com.hazelcast.concurrent.countdownlatch.client.CountDownLatchPortableHook$1@60d09d45

This happens if you have different hazelcast jars in you classpath. But I made sure i don't have any other version. It still fails. I even tried excluding spring-boot HazelcastAutoConfiguration.class which might start its own instance, but still no luck.

Any clue?

This workaround seems to be working- Creating a simple GlassFish service to use Hazelcast fails
