Masafumi Miura updated WFLY-9365:
---------------------------------
Steps to Reproduce:
# Execute add-user.sh to create a JMS user
{code}
./bin/add-user.sh -a -u 'test' -p 'test at 123' -g 'guest'
{code}
# Start WildFly 11.0.0.CR1 with standalone-full-ha.xml
# Execute jboss-cli to create a JMS Queue
{code}
jms-queue add --queue-address=testQueue --entries=queue/test,java:jboss/exported/jms/queue/testQueue
{code}
# Extract the attached reproducer
# Copy {{$JBOSS_HOME/bin/client/jboss-client.jar}} under {{lib/}} directory
# Execute {{mvn initialize}} to install it in local maven repo
{code}
mvn initialize
{code}
# Execute a producer (or consumer)
{code}
mvn compile exec:java -Dexec.mainClass=com.redhat.jboss.support.example.client.JGroupsDiscoveryProducer -Djava.net.preferIPv4Stack=true -Djgroups.bind_addr=127.0.0.1 -Djava.util.logging.config.file=custom-logging.properties
{code}
{code}
mvn compile exec:java -Dexec.mainClass=com.redhat.jboss.support.example.client.JGroupsDiscoveryConsumer -Djava.net.preferIPv4Stack=true -Djgroups.bind_addr=127.0.0.1 -Djava.util.logging.config.file=custom-logging.properties
{code}
Then, you will see NPE repeatedly.
