On jenkins with the upcoming 7.4.10 one can notice, at a specific testsuite (undertow-integration) with jdk8, a lot of WFLYPRT0053 errors which do not exist in previous version 7.4.9 :
java.net.ConnectException: WFLYPRT0053: Could not connect to remote+
The connection failed at org.jboss.as.protocol.ProtocolConnectionUtils.connectSync(ProtocolConnectionUtils.java:129)
It could be possible that this could be caused via a potential leak .....
