removeUser works well in this case (Method called during startup) :

public class BoostrapUsers {


    @PersistenceContext(type = PersistenceContextType.EXTENDED)
    private EntityManager entityManager;

    @Inject
    private IdentityManager identityManager;

    /**
     * <p>Loads some users during the first construction.</p>
     */
    //TODO this entire initialization code will be removed
    @PostConstruct
    public void create() {
        JPAIdentityStoreContext.set(this.entityManager);

        User user = this.identityManager.createUser("admin");
        User user1 = this.identityManager.createUser("user1");



        this.identityManager.updateCredential(user, new PasswordCredential("admin"));
        this.identityManager.updateCredential(user1, new PasswordCredential("user1"));
        Role roleDeveloper = this.identityManager.createRole("simple");
        Role roleAdmin = this.identityManager.createRole("admin");

        Group groupCoreDeveloper = identityManager.createGroup("Default Users Group");

        identityManager.grantRole(roleDeveloper, user, groupCoreDeveloper);
        identityManager.grantRole(roleDeveloper, user1, groupCoreDeveloper);
        identityManager.grantRole(roleAdmin, user, groupCoreDeveloper);
        
        identityManager.removeUser("user1");
        
        JPAIdentityStoreContext.clear();
    }

}

but when calling removeUser in my project, it removes all the users :

 public void removeUser(String name){
       User user = identityManager.getUser(name);
        if(user != null){
            identityManager.removeUser(user); // all users are now deleted
         }

    }

I can see in the logs that the SQL delete statement is called for each user record
