I have an application that uses CDI and JAX-RS but not MP REST. The MP subsystems aren't even part of the WildFly configuration. Nonetheless, the MP REST client is added to the deployment and creates a classloader leak when the application is undeployed.
See below for the paths to GC root, as determined using a heap dump analyzed by Eclipse MAT. In particular, note that org.jboss.resteasy.microprofile.client.RestClientExtension keeps a static reference to the CDI BeanManager.
Workaround: add an exclusion in jboss-deployment-structure.xml to prevent the org.jboss.resteasy.resteasy-client-microprofile module from being added to the deployment.
