[jboss-jira] [JBoss JIRA] Reopened: (JBMESSAGING-1749) Support null values for javax.jms.MapMessage.setObject

Support null values for javax.jms.MapMessage.setObject ------------------------------------------------------ Key: JBMESSAGING-1749 URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1749 Project: JBoss Messaging Issue Type: Feature Request Components: Messaging Core Affects Versions: 1.4.0.SP3.CP09, 1.4.6.GA Reporter: Justin Bertram Assignee: Howard Gao Fix For: 1.4.0.SP3.CP10, 1.4.6.GA.SP1, 1.4.7.GA Our implementation of javax.jms.MapMessage is org.jboss.jms.message.JBossMapMessage. Its setObject is: public void setObject(String name, Object value) throws JMSException { checkName(name); if (value instanceof Boolean) ((Map)getPayload()).put(name, value); else if (value instanceof Byte) ((Map)getPayload()).put(name, value); else if (value instanceof Short) ((Map)getPayload()).put(name, value); else if (value instanceof Character) ((Map)getPayload()).put(name, value); else if (value instanceof Integer) ((Map)getPayload()).put(name, value); else if (value instanceof Long) ((Map)getPayload()).put(name, value); else if (value instanceof Float) ((Map)getPayload()).put(name, value); else if (value instanceof Double) ((Map)getPayload()).put(name, value); else if (value instanceof String) ((Map)getPayload()).put(name, value); else if (value instanceof byte[]) ((Map)getPayload()).put(name, ((byte[]) value).clone()); else throw new MessageFormatException("Invalid object type."); } Setting a null value will result in a MessageFormatException since instanceof returns false on nulls. Although the JMS spec doesn't indicate its necessity, I think we should support setting null values (e.g. javax.jms.MapMessage.setObject("name", null)) as this is a convenience method support both by WebLogic and WebSphere.
