UndertowRequestUpgradeStrategy not compatible with WildFly anymore [SPR-13619]

[spring-projects-issues]

Juergen Hoeller opened SPR-13619 and commented

The changes triggered by #18106 kept UndertowRequestUpgradeStrategy compatible with Undertow 1.3 standalone and embedded, but broke general compatibility with WildFly due to an odd side effect of proxy class instantiation with WildFly's strict ClassLoader - on some JVMs at least. Let's fix this for 4.2.3 through reverting back to the regular inner class for the HttpUpgradeListener in our upgradeInternal implementation, keeping the rest of our reflective adaptation in place for general Undertow 1.2 vs 1.3 bridging.
