[jira] [Commented] (KARAF-5054) Default rmiRegistryPort 1099 is used always besides different configuration

Jean-Baptiste Onofré commented on KARAF-5054:
---------------------------------------------

It sounds like a race condition where the configuration is loaded after the activator start. Let me try to reproduce.

> When starting a _clean_ karaf instance (either very first first start or with {{clean}} command line parameter) the karaf management feature always tries to open the default port {{1099}} before opening the configured port resulting in a confusing exception in the {{karaf.log}}:

> if the port is already used by another process (e.g. another karaf instance).
> The configured port {{rmiRegistryPort = 1100}} in the config file  {{org.apache.karaf.management.cfg}} will be nevertheless applied afterwards.
> This can easily reproduced by creating two instances of the standard karaf {{4.1.0}} binary distributions and applying above configuration to the second instance.
> This occurs on _Windows_ (7 64 bit tested) only, and can *not* be reproduced on _Linux_ OS!
> The same behavior (of using the default port before the differently configured one) has been observed for other ports as of: rmi server port ({{rmiServerPort}} in {{org.apache.karaf.management.cfg}}) and ssh ({{sshPort}} in {{org.apache.karaf.shell.cfg}}. Depending on the logging configuration the failing usage of the default ports can be seen before the configured ports are taken into account.
> Re-configuring the ports at runtime via the configuration properties works fine!
