[jboss-jira] [JBoss JIRA] Assigned: (JBWEB-150) Provide an identifier to relate web application to classloader in a heap dump

Provide an identifier to relate web application to classloader in a heap dump ----------------------------------------------------------------------------- Key: JBWEB-150 URL: https://jira.jboss.org/jira/browse/JBWEB-150 Project: JBoss Web Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Core Reporter: Mike Millson Assignee: Remy Maucherat Attachments: jbossweb_2_0_0_CP03-add_display_name.txt, JBWEB-150-patch.txt, testbox.war When troubleshooting OutOfMemoryError issues in situations where the JVM is running multiple applications, it would be very helpful for troubleshooting to be able to relate a web application to the web app classloader. It is proposed to sets the display-name of the war as a property on the web app classloader so that it can be easily accessed when viewing a heap dump (e.g. with a tool such as the Eclipse Memory Analyzer Tool). For example, given the following web application deployment descriptor (web.xml): <web-app> <display-name>Testbox</display-name> </web-app> Inspection of the corresponding org.jboss.web.tomcat.service.WebAppLoader and org.jboss.web.tomcat.service.WebAppClassLoader objects in the heap dump will show "Testbox" in the displayName field.
