Jörg Hoh created SLING-4390:
-------------------------------
Summary: webapp deployment: properties in sling.properties
overrule web.xml init parameters
Key: SLING-4390
URL: https://issues.apache.org/jira/browse/SLING-4390
Project: Sling
Issue Type: Bug
Components: Launchpad
Affects Versions: Launchpad Base 2.5.6
Reporter: Jörg Hoh
The documentation [1] explictly states, that any parameter in the web.xml will
overwrite the variable with the same in sling.properties.
But looking at the code in Sling.java, I find, that into the init() method the
parameters from the web.xml are passed in via the propOverwrite map. This map
is first applied, and then the sling.properties (if available) is read and
applied.
This violates both the documentation on site [1] and also the javadoc of the
class.
The impact can be rather huge, as it isn't possible to update parameters which
are stored in the sling.properties already with a new version of the web,xml
contained in the WAR file. But we need to update the sling.properties file
manually.
