[jira] Commented: (MODELER-15) [modeler] IntrospectionUtils memory leak

["Bill Barker (JIRA)" <ji...@apache.org>]

    [ http://issues.apache.org/jira/browse/MODELER-15?page=comments#action_12414675 ] 

Bill Barker commented on MODELER-15:
------------------------------------

A method has been added to IntrospectionUtils to clear the cached methods (similar to the one in the Tomcat class that this was stolen from :).  Of course, it won't have any effect until the next release of Modeler, and after that when the Tomcat team decides to upgrade to it.

However, this has already been fixed for Tomcat 6.x with an independent patch.

> When I reload my webapp, and I profile, I see Method objects in 
> IntrospectionUtils grow and grow (to the thousands of instances), and none of 
> my class Objects (or static references) get collected.
> This is in the objectsMethods HashTable.
> One suggestion: remove the caching
> or
> Another suggestion: add a method that clears it (or clears it for a certain 
> classloader), and make sure this method gets called from Tomcat when it 
> unloads a webapp (since I dont know how a webapp could call this method if 
> this class is loaded from the system classloader)
