Subject [jira] [Updated] (TOMEE-1863) Log4J initialized twice for web app
Date Mon, 11 Jul 2016 19:12:11 GMT

     [ https://issues.apache.org/jira/browse/TOMEE-1863?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

loua updated TOMEE-1863:
------------------------
    Description: 
The web application uses slf4j for logging.  The logging implementation is log4j.  The application
contains a log4j.properties file in the WEB-INF\classes directory.  The application uses JAX-RS
and Stateless EJBs.  Log4j is initialized by the TempClassLoader and then again when the webapp
is loaded.  This results in two OS file handles referencing the same log file (RollingLogFileAppender)
that prevents the log file from rolling over.  TomEE logging uses the default java.util.logging.
