-=== Don't Use `AuthorizationManager` in Method Security
-
-To opt out of `AuthorizationManager` for Method Security, replace xref:servlet/authorization/method-security.adoc#jc-enable-method-security[method security] with xref:servlet/authorization/method-security.adoc#jc-enable-global-method-security[global method security]
