Summary: Statement Cache Bug
Initial Comment:
Running JBoss 4.0.0, I have a datasource with:
<prepared-statement-cache-size>32</prepared-statement-cache-size>
I get the following exception:
2004-10-21 14:57:25,987 ERROR
[org.jboss.web.localhost.Engine]
StandardWrapperValve[ProInsight Servlet]:
Servlet.service() for servlet ProInsight Servlet threw
exception

This does not occur with JBoss 3.2.6 and does not occur
if disable the statement cache in JBoss 4.0.0
