Arquillian test in arquillian-tomee-webprofile-tests that deploys a Facelet combining c:set in request scope with an EL reference to the implicit param map. Passes on tomee-embedded and reproduces the LinkageError on Map$$OwbNormalScopeProxy under the remote adapter (-Pall-adapters).
…finer When the JVM rejects a defineClass with LinkageError because that class name is already loaded in this ClassLoader, re-resolve the existing class via Class.forName instead of failing. Mirrors the Unsafe.handleLinkageError fallback in OpenWebBeans, which only kicks in when no DefiningClassService is registered. Without this defence OpenWebBeans 4.0.x can generate the same proxy class FQN for two distinct Bean<?> instances of the same erased type (e.g. MyFaces' @FacesScoped Map producers requestScope/param/header/...) and the LinkageError propagates to the user. Logs a WARNING so the recovery remains visible.
