UDP Syslog handler cannot log first message after reconnect

1) Configure EAP to log some category to syslog through UDP: <syslog-handler name= "SYSLOG" > <server-address value= "127.0.0.1" /> <hostname value= "-" /> <port value= "10514" /> <app-name value= "JBossEAP" /> <formatter> <syslog-format syslog-type= "RFC5424" /> </formatter> <facility value= "local-use-5" /> </syslog-handler> ... <logger category= "org.jboss.as.test.integration.logging.operations" > <level name= "INFO" /> <handlers> <handler name= "SYSLOG" /> </handlers> </logger> 2) Start application server and syslog server. 3) Deploy logging servlet (see attachements) which makes one log when is accessed. 4) Access http://127.0.0.1:8080/logging-deployment/logger -> message is logged to syslog 5) Stop Syslog server 6) Access http://127.0.0.1:8080/logging-deployment/logger 0, 2, 4 times... (message is not logged to syslog since it is down) 7) Start Syslog server 8) Access http://127.0.0.1:8080/logging-deployment/logger -> message is logged to syslog (correct behavior) 9) Stop Syslog server 10) Access http://127.0.0.1:8080/logging-deployment/logger 1, 3, 5 times... (message is not logged to syslog since it is down) 11) Start Syslog server 12) Access http://127.0.0.1:8080/logging-deployment/logger -> message is NOT logged to syslog (wrong behavior) 13) Access http://127.0.0.1:8080/logging-deployment/logger again -> message is logged to syslog
