Summary

0036001: Connection leak after start the system having any servlet with "loaded-on-startup" for example: Analytics module installed

DescriptionA transaction is not closed after restart tomcat when the instance has Analytics module installed.

The problem occurs for any Servlet that is marked to be loaded on startup, at this point a DAL connection is now created out of a Servlet request, so standard DalThreadHandler is not closing it.
Steps To ReproduceIn an environment with Analytics module installed:

1- Start tomcat

Check on the pg_stat_activity that there is a line in state='idle in transaction'

the query is:

SELECT mo.action AS TYPE, (CASE mo.action WHEN 'X' THEN mo.ad_form_id WHEN 'P' THEN mo.ad_process_id WHEN 'R' THEN mo.ad_process_id WHEN 'S' THEN mo.ad_reference_id WHEN 'C' THEN mo.ad_callout_id ELSE null END) AS ID, m.name AS NAME, /*Name is only maintained for backwards compatibility, now REPORT_TITLE is automatically filled*/ COALESCE((CASE mo.action WHEN 'X' THEN f.ad_module_id WHEN 'P' THEN p.ad_module_id WHEN 'R' THEN p.ad_module_id WHEN 'S' THEN r.ad_module_id W

Having Analytics installed this query is launched in the init method of the QueryRepositoryServlet servlet
Proposed SolutionBeing this query executed on Servlet's init method, which is typically executed just once per class, the overhead of using an extra connection for 1st execution is small. So reverting init part of changeset for 0035855 is safe in this case.

 It seems that it can be reproduced always when the Analytics module is present.
