> The ConfigurationAdmin.listConfigurations implementation accesses the configuration persistence managers to get all configurations and returns these configurations. That is, the Configuration objects returned are not backed by the same data as is cached inside the ConfigurationManager. When such a listed configuration is then updated, it is persisted, but the internally cached configuration data does not reflect the changes.
> This issue may be illustrated with this test code:
>      ConfigurationAdmin ca = getConfigurationAdmin();
>      // initialize configuration
>      Dictionary dict = new Hashtable();
>      dict.put("sample", "old_value");
>      ca.getConfiguration("sample.pid").update(dict);
>      // modify the listed configuration
>      Configuraiton[] cfg = ca.listConfigurations("service.pid = sample.pid");
>      Dictionary dict = cfg[0].getProperties();
>      dict.put("sample", "new_value");
>      cfg[0].update(dict);
>     Configuration config = ac.getConfiguration("sample.pid");
>     Object theValue = config.getProperties().get("sample");
> The theValue variable is expected to contain "new_value" but actually contains "old_value".
> Thanks to Tom Remoleur for reporting this issue and providing the test case.
