[jboss-jira] [JBoss JIRA] Closed: (JBAS-3401) NPE in jdk5 javax.management.MBeanOperationInfo.equals() (affects jmx-console)

NPE in jdk5 javax.management.MBeanOperationInfo.equals() (affects jmx-console) ------------------------------------------------------------------------------ Key: JBAS-3401 URL: http://jira.jboss.com/jira/browse/JBAS-3401 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: Management services Reporter: Dimitris Andreadis Assigned To: Dimitris Andreadis Fix For: JBossAS-5.0.0.Beta The javax.management.MBeanOperationInfo.equals() of jdk5 produces NPEs when any field of the "other" object is null: public boolean equals(Object o) { if (o == this) return true; if (!(o instanceof MBeanOperationInfo)) return false; MBeanOperationInfo p = (MBeanOperationInfo) o; return (p.getName().equals(getName()) && p.getReturnType().equals(getReturnType()) && p.getDescription().equals(getDescription()) && p.getImpact() == getImpact() && Arrays.equals(p.fastGetSignature(), fastGetSignature())); } This could be a jdk bug, however the problem appears in when viewing the MainDeployer mbean through the jmx-console, due to the descriptor field of some "deploy" operation being null in the xmbean descriptor. org.apache.jasper.JasperException: Exception in JSP: /inspectMBean.jsp:94 91: { 92: MBeanOperationInfo opInfo = operationInfo[a]; 93: System.out.println(String.valueOf(a) + opInfo); 94: operationInfoIndexMap.put(opInfo, String.valueOf(a)); 95: } 96: 97: Arrays.sort(operationInfo, MBEAN_FEATURE_INFO_COMPARATOR); root cause java.lang.NullPointerException javax.management.MBeanOperationInfo.equals(MBeanOperationInfo.java:209) java.util.HashMap.eq(HashMap.java:277) java.util.HashMap.put(HashMap.java:386) org.apache.jsp.inspectMBean_jsp._jspService(inspectMBean_jsp.java:155) org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) The problem doesn't affect Branch_4_0, since the inspectMBean.jsp code is different
