title: JGoodies memory leak?? - Out of Memory Exception when Spring tries to display the view
body: <p>I am getting an Out of Memory exception sometimes during or after the validation of component happens.  I was trying to profile a large validation result &lt;= 20000, and it worked, so I went bigger.  The exception occurs at values > 20000, does anyone know of any inherent jgoodies memory leaks, with the validation framework, the component binder, or anything else? </p>
