not sure if your issue is resolved,
we had a similar issue recently, and its fixed by adding context-path property in application.properties.
1. so, if your applicatiion.properties has a context-path key then antmatchers should start with just path mapping (start with /)
2. if you don't have a context defined in application.properties, but with a RequestMapping in your restconroller, then antmatchers should always include context-path (again, start with /)
i hope this resolves your issue,
Note: there is a change in the context-path spring property with jdk 11
