Couldn't destroy threadgroup ... IllegalThreadStateException
See original GitHub issueFollowing the first maven example in Chapter1. The operation is successful with the file copy, but throws WARNING afterwards. Happened both with Maven 3.3.1 and 3.5.0 (I don’t have 3.3.3 on MacOs)

The only way to avoid the error is to add -Dexec.cleanupDaemonThreads=false to the launch command:
mvn compile exec:java -Dexec.mainClass=camelinaction.FileCopierWithCamel -Dexec.cleanupDaemonThreads=false
Still the same Exception with Camel 2.19.1, Java 1.8.0_131, mvn 3.5.0
