[jira] [Commented] (FELIX-4373) Felix does not appear to set org.osgi.* values as System properties

["Felix Meschberger (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FELIX-4373?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13862855#comment-13862855 ] 

Felix Meschberger commented on FELIX-4373:
------------------------------------------

IMHO the framework is not to set the system properties just to manage the framework properties.

Setting system properties is a VM-wide operation which may be causing trouble if you have multiple OSGi frameworks running within the same VM.

As to the spec: I would assume the intent is to set the framework properties and not the system properties as well.

As such, I would expect the Felix Framework implementation to do the right thing (not setting the system properties) and the Felix Gogo shell to do the right thing (to no expose framework properties for the getProperties call.

> From the command line console, the value returned by context:getProperty appears to differ from the property set on the JVM:
> g! (getProperties) get "java.version"
> 1.7.0_45
> g! (getProperties) get "org.osgi.supports.framework.extension"
> g! context:getProperty "java.version"
> 1.7.0_45
> g! context:getProperty "org.osgi.supports.framework.extension"            
> true
> g! (getProperties) get "org.osgi.framework.version"
> g! (getProperties) get "org.osgi.framework.vendor"
> g! context:getProperty org.osgi.framework.version
> 1.5
> g! context:getProperty org.osgi.framework.vendor
> Apache Software Foundation
> It looks like context:getProperty is doing something different than that returned by System.getProperties(). On the other hand, when running under Equinox, these both return the same result:
> osgi> context:getProperty org.osgi.supports.framework.extension
> true
> osgi> (getProperties) get "org.osgi.supports.framework.extension"
> true
> osgi> (getProperties) get "org.osgi.framework.vendor"
> Eclipse
> osgi> (getProperties) get "org.osgi.framework.version"
> 1.7.0
> From the OSGi specification:
> "Additionally, frameworks must implement fragments, require bundle, and extensions. They must therefore set the following properties to true.
> org.osgi.supports.framework.requirebundle org.osgi.supports.framework.fragments
> org.osgi.supports.framework.extension"
> It is not clear if the spec suggests the properties should be set as System properties, or merely the system bundlecontext's properties (which is what Felix appears to do).
