Writing your own is very simple, take a look at the code for the
StatementFinalizer

http://svn.apache.org/viewvc/tomcat/tc7.0.x/trunk/modules/jdbc-pool/src/main/java/org/apache/tomcat/jdbc/pool/interceptor/StatementFinalizer.java?view=markup

And you can easily add in options to track stack traces.
