> 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.
