Our application works with ActiveMQ message broker, but we need to check it works with other brokers. When I've setuped application to work with JBM, application failed on sending message. It caused by NPE: anonymous wrote : Caused by: java.lang.NullPointerException | at org.jboss.messaging.util.TypedProperties.containsProperty(TypedProperties.java:151) | at org.jboss.messaging.core.message.impl.MessageImpl.containsProperty(MessageImpl.java:285) | at org.jboss.messaging.jms.client.JBossMessage.propertyExists(JBossMessage.java:506) | I think it's a bug. Is there a workaround of it? Version of JBM - 2.0.0.alpha1 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4166919#...
