Log4jConfigurer prevents reload of war [SPR-17]

[spring-projects-issues]

Peter Reinhardt opened SPR-17 and commented

A web application using the Log4jConfigServlet cannot be reloaded. The Log4jConfigurer uses the class WebUtils to set the WebappRoot (as a system property). If this property is already set, an IllegalStateException is thrown.

This condition is true if the same web app is loaded twice (i.e. if a servlet class changes or a jsp file). This functionality is core to any app server.

Affects: 1.0 M4

This was a bug introduced in 1.0 M4. Already fixed in CVS, to be released in RC1. Now, the exception only gets thrown if attempting to change the system property to a different value, which should never be the case on redeployment of the same web app.
