I am newbie to ironjacamar . I am trying to debug an issue of slow leak in jdbc connections . we are using wildlfy10 which uses ironjacamar. I am trying to find who is the culprit. Here is the log with tracer turned on. i did generate the html report But want to under stand which application code is causing the issue.

Hi,
you can try leak detector pool [1] instead of tracer. In WildFly you can enable it with command:
/subsystem=datasources/data-source=<datasource_name>:write-attribute(name=mcp, value="org.jboss.jca.core.connectionmanager.pool.mcp.LeakDumperManagedConnectionPool")

If you don't specify property "ironjacamar.leaklog", it logs to standard wildfly log ($WILDFLY_DIST/standalone/log/server.log)
