Unable to set checkInterval init-param to 0 for 'jsp' servlet
-------------------------------------------------------------

                 Key: JBAS-7479
                 URL: https://jira.jboss.org/jira/browse/JBAS-7479
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Web (Tomcat) service
    Affects Versions: JBossAS-5.1.0.GA, JBossAS-4.2.3.GA
            Reporter: James Livingston
            Assignee: Remy Maucherat


If you attempt to set the checkInterval init-param to 0 in jboss-web.deployer/conf/web.xml (4.2) or deployers/jbossweb.deployer/web.xml (5.1) you receive a warning 'Warning: Invalid value for the initParam checkInterval. Will use the default value of "300" seconds' despite the comments indicating it is a valid value.

What seems to have happened is that a while back we copied the org.apache.jasper.EmbeddedServletOptions class to org.jboss.web.tomcat.service.jasper.JspServletOptions so that we could override tldLocationsCache. Some time later, a Tomcat bug[0] in that class got fixed, but our copied code didn't get the fix applied.


The relevant change is removing the "if (this.checkInterval == 0)" block, so that 0 is an acceptable value. If we did want to disallow 0, then it is buggy because it gets left as 0 if the init-param is not present or is a non-numeric value.
