NPE in Quarkus application with InfiniSpan cache and JPA configured as its persistence store

Question

I am trying to configure hibernate-orm as persistence store to InfiniSpan cache. I have CacheManager as below:

GlobalConfigurationBuilder globalConfigBuilder = GlobalConfigurationBuilder.defaultClusteredBuilder();
globalConfigBuilder.transport().clusterName("AetherInfini");
DefaultCacheManager cacheManager = new DefaultCacheManager(globalConfigBuilder.build());

And cache configuration:

ConfigurationBuilder cacheConfigBuilder = new ConfigurationBuilder();
cacheConfigBuilder
        .clustering()
        .cacheMode(CacheMode.REPL_ASYNC)
        .persistence()
        .addStore(JpaStoreConfigurationBuilder.class)
        .persistenceUnitName("<default>")
        .entityClass(MyClass.class)
        .segmented(false);
cacheManager.defineConfiguration("my-name", cacheConfigBuilder.build());

It ran into an NPE:

ERROR [io.qua.run.Application] (main) Failed to start application (with profile prod): java.lang.NullPointerException

I have hibernate-orm configuration in application.properties. Therefore there is no explicit persistence-unit name. I found <default> is the name in Quarkus (?).

Can someone tell me what is wrong or point me to related documents? Thank you.
