Insight threw exception Handler processing failed; nested exception is java.lang.

Hi,

I have created a spring insight plugin(insight-plugin-epm-1.5.0.RELEASE.jar) for my java servlet application....and I am just wondering the cause of the following problem....java.lang.StackOverflowError..

Code:

Aug 29, 2011 12:16:39 PM org.apache.catalina.core.StandardWrapperValve invoke SEVERE: Servlet.service() for servlet [Spring MVC Dispatcher Servlet] in context with path [/insight] threw exception
