> Hello Apache Struts Team.
> This Jira proposes to provide some cache-clearing methods for the OgnlUtil
> class, as well as methods to check the current cache element count.
> These methods will allow applications to clear the OgnlUtil expression cache
> and BeanInfo cache when necessary (using application-specific usage profile).
> Currently the only OgnlUtil cache control available to applications is to
> enable/disable the OgnlUtil expressionCache
> ({{struts.ognl.enableExpressionCache flag}}).
> Using the new methods applications that have resource (memory) leak issues
> with the caches may be able to use the caches to gain some performance
> benefits, while periodically clearing them to recover memory resources.
> Application developers can determine how frequently (e.g. hourly, daily) such
> cache clearing is needed.
