[jira] [Resolved] (KARAF-1070) Allow recusive variable references to be applied as substitution then assignment

["Andreas Pieber (Resolved) (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/KARAF-1070?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andreas Pieber resolved KARAF-1070.
-----------------------------------

    Resolution: Not A Problem

the bootdelegation property between the system and custom file are already aggregated. There's no need for referencing them again.

> Hi,
> I tried adding the following to custom.properties:
> {noformat}
> org.osgi.framework.bootdelegation = ${org.osgi.framework.bootdelegation}, org.bouncycastle.*
> {noformat} 
> In the hope that it would do substitution then assignment, but I get an illegal arg exception "recursive variable reference: org.osgi.framework.bootdelegation"  (at org.apache.karaf.main.Main.substVars(Main.java:1201))
> If the above were possible our custom distro would extend rather than overwrite the standard Karaf settings - which would make custom distros a bit more resilient (I'm somewhat fearful I'll miss a change in config, even when running diffs on the stock and custom cfg files).
> (btw creating a custom distro is incredibly easy and a really cool feature, thanks)
