In 15.12. Extending the Identity component, there is an example of extending a SEAM-Component. It is said:

The install precendence of APPLICATION ensures that this extended Identity gets installed in preference to the built-in Identity.

But when I do this:

@Name("org.jboss.seam.security.jpaIdentityStore")
@Install(precedence = org.jboss.seam.annotations.Install.APPLICATION)
@Scope(APPLICATION)
@BypassInterceptors
@Startup
public class MyIdentityStore implements IdentityStore, Serializable
{

then this failure occurs:

java.lang.IllegalStateException: Two components with the same name and precedence - component name: org.jboss.seam.security.jpaIdentityStore, component classes: com.MyIdentityStore

when I do this, then MyIdentityStore is installed:

@Name("org.jboss.seam.security.jpaIdentityStore")
@Install(precedence = DEPLOYMENT)
@Scope(APPLICATION)
@BypassInterceptors
@Startup
public class MyIdentityStore implements IdentityStore, Serializable
{

However, then I can find in my Application Scope, both MyIdentityStore and JpaIdentityStore. Is that okay?
