Changed to use AopUtils.getMostSpecificMethod() when obtaining the method on which the parameter resolution should be performed. Also added better error handling and log warning when parameter names cannot be resolved. The exception will then be a SpEL one, rather than a NPE.
CompositeName adds quotes to names which contain a forward slash ("/") character. These are automatically removed by Spring LDAP's DistinguishedName, but only if they are at the ends of the String. Since we were preprending the base to the (quoted) DN, resulting in something like ["cn=joe/b",ou=people], this was causing problems with the DN value returned from the search. Additionally, the bind succeeds when a DN is used with a slash, but the subsequent call to getAttributes() fails. This call now passes in a DistinguishedName for the user DN instance instead of a String.
It now votes to abstain if there are no Jsr250 attributes present. If any are found, it will either deny or grant access. For multiple "RoleAllowed" attributes, access will be granted if any user authority matches or denied if no match is found.
This results in the method BeanUtils.findEditorByConvention attempting to get hold of the system classloader which isn't allowed by the security manager in GAE.
Also deprecated the existing AspectJ interceptors. This will also allow future simplification of the AbstractMethodSecurityMetadataSource, as it no longer needs to support JoinPoints.
MethodSecurityMetadataSourceAdvisor now takes the SecurityMetadataSource bean name as an extra constructor argument and re-obtains the bean from the BeanFactory in its readObject method. Beans that are advised using <global-method-security> should therefore now be serializable.
The browser (or at least Firefox) does not send it after a redirect, and it causes problems with Spring's ShallowEtagHeaderFilter if it is stored and returned by the saved request.
Converted test target to implement ApplicationListener<SessionCreatedEvent> so that it doesn't receive events from its own interceptor (which are in turn intercepted).
Using ":" as the token delimiter means we accidentally mistake the URL for two tokens. This had previously been fixed for http URLs but not https ones.
The user is then seen as being authenticated to further (re-entrant) requests which occur before the existing request has completed. The saving logic is contained with the SecurityContextRepository implementation.
