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

[Mike Millson (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBWEB-150?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mike Millson updated JBWEB-150:
-------------------------------

    Description: 
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.
