I have a trouble deploying my sprint-boot application (converted tp .war) in liberty 8.5:
Failed to instantiate [javax.persistence.EntityManager]:
Factory method 'createSharedEntityManager' threw exception;
nested exception is java.lang.LinkageError: loader constraint violation:
loader (instance of com/ibm/ws/classloading/internal/ThreadContextClassLoader)
previously initiated loading for a different type with name
"org/eclipse/persistence/expressions/Expression"
But when I run my spring-boot application packaged as .jar it works.
My persistence is
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence

Class Database Config
@Configuration
@EnableTransactionManagement
@EnableConfigurationProperties(DbAuthenticationProperties.class)
@EnableJpaRepositories(basePackages = {"com.bank.arc.commons.dao.repository"},
entityManagerFactoryRef = "authenticationDbEntityManagerFactory",
transactionManagerRef = "authenticationDbTransactionManager")
public class DbAuthenticationConfig extends DbConfig {
@Autowired
private DbAuthenticationProperties properties;
@PostConstruct
public void init() {
super.setProperties(properties);
}
@Bean
@Primary
public DataSource authenticationDbDataSource() {
return super.dataSource();
}
@Bean
@Primary
public LocalContainerEntityManagerFactoryBean authenticationDbEntityManagerFactory() {
return super.entityManagerFactoryBean(authenticationDbDataSource(), authenticationDbJpaVendorAdapter(), "authentication");
}
@Bean

return super.jpaVendorAdapter(DatabasePlatform.DB2);
}
@Bean

return super.transactionManager(authenticationDbEntityManagerFactory());
}
}
And the server.xml:
<server description="new server">

<!-- Automatically expand WAR files and EAR files -->
