DescriptorSupport does not validate its serializable fields adequately ---------------------------------------------------------------------- Key: JBAS-1268 URL: http://jira.jboss.com/jira/browse/JBAS-1268 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Reporter: Scott M Stark Assigned To: Scott M Stark Fix For: JBossAS-3.2.7 Final, JBossAS-4.0.2RC1 Original Estimate: 1 hour Remaining Estimate: 1 hour Although the javax.management.modelmbean.DescriptorSupport does attempt to validate whether its fields are Serializable, it does not validate all of the values references. This causes failures when accessing mbeans over rmi as shown in this twiddle example: [starksm@banshee9100 bin]$ twiddle.sh -s lamia:1099 invoke "jboss.web:service=WebServer" stopConnectors
