[jira] [Resolved] (ACE-445) Add an option to the launcher to set system properties

["J.W. Janssen (JIRA)" <ji...@apache.org>]

J.W. Janssen resolved ACE-445.
------------------------------

    Resolution: Fixed

Committed a fix in rev #1575269:
- simplified the launcher in the handling and setting of configuration properties:
-* (almost) all configuration properties are now passed to the OSGi framework as framework property, except for properties starting with 'system.', which are set as system property;
-* the 'framework.' prefix is deprecated, as it is no longer needed, but the launcher still will strip off this prefix if supplied;
-* agent configuration properties are now regarded as framework properties, and the agent now uses BundleContext#getProperty() to obtain its configuration options;
-* updated and clarified the help text of the launcher.
- allow configuration options to be set as *normal* arguments of the launcher itself, as well as system property, so, '-Dfoo=bar' and 'foo=bar' both will work;
- simplified the semantics of the agent with respect to its configuration handling: system properties are now regarded as default values that can be superseded by explicitly configured values (through framework properties, or explicit configuration). The '.retain' suffix for system properties to always supersede framework properties is removed, as it is quite difficult to explain and understand how they should work.

Please close if you're satisfied with the solution.

> The launcher supports an option file that can set various kinds of properties, but no system properties. Add an option to set them (via a "system." prefix).
