Why does the wildfly server started from the wildfly-maven-plugin not shutdown? - shutdown

Question

I start a wildfly server from the wildfly-maven-plugin in order to perform integration-tests.
Every once in a while, the server does not shut down properly, and the java process does not terminate.
I get:
WARN [org.jboss.as.controller] (ServerService Thread Pool -- 24) JBAS014618: Graceful shutdown of the handler used for native management requests did not complete within [15000] ms but shutdown of the underlying communication channel is proceeding
Any idea how to fix this?
BR,
Stefan
I looked into the TRACE log of the server, but could not find something that helped me:
