------------------------------------
Summary: No override facility for properties in system.properties
Key: KARAF-5440
URL: https://issues.apache.org/jira/browse/KARAF-5440
Project: Karaf
Issue Type: Bug
Components: karaf-core
Reporter: Tom Quarendon
Priority: Minor
There are two properties files in karaf that give global properties of various
kinds, system.properties and config.properties.
The "config.properties" file has a facility to override properties within it by
putting values in the "custom.properties" file. We use this to tweak certain
values in out custom distribution.
There's no such facility though for the "system.properties" file.
At the moment we therefore hold a copy of the whole system.properties file with
a couple of modifications and include that in our distribution. This is fragile
though. For example, recently one of the properties was changes by a commit to
karaf and it took me a while to work out why things suddenly started behaving
differently (this isn't a criticism, I'm just pointing out the fragility, in
case it wasn't clear).
It looks like there wouldn't be any particular reason why this couldn't be done
by org.apache.karaf.util.config.PropertiesLoader. I'm happy to provide a pull
request for consideration. I would have suggested having an ${optionals} line
in the system.properties file that would load a file called, say,
custom.system.properties. I would have just replaced the code to load the
properties in loadSystemProperties with a call to loadPropertiesFile.
