Grails 7.0.0-M3: Ambiguous method overloading for method GrailsControllerUrlMappings#matchAll

[Taack]

Expected Behavior

The test app should mostly work.

Actual Behaviour

When trying accessing our test app with Grails 7.0.0-M3, the following error occurs:

2025-03-10 04:42:34.211 ERROR --- [nio-9442-exec-7] t.support.TaackUiEnablerInterceptor      : Access Denied: login auth Ambiguous method overloading for method org.grails.web.mapping.mvc.GrailsControllerUrlMappings#matchAll.
Cannot resolve which method to invoke for [class java.lang.String, null, class java.lang.String] due to overlapping prototypes between:
        [class java.lang.String, class java.lang.String, class java.lang.String]
        [class java.lang.String, class org.springframework.http.HttpMethod, class java.lang.String], __grails.anonymous.user__, [controller:login, action:auth]

The error occurs either with bootRun or with the bootJar, jar.

Steps To Reproduce

The test case is available at https://github.com/Taack/infra/tree/g7M3.

To launch it, under the g7M3 branch:

cd taack-ui-test
./gradlew bootRun

Environment Information

JDK: Correto 17

Groovy: 4.0.25

Example Application

Version

Digging into this issue, it is caused by grailsRequest.currentRequest.method being null in grails/plugin/springsecurity/ReflectionUtils.groovy.

It might be a Groovy bug (method is clearly a String), I will try using Groovy 4.0.26.
