You don't have to worry that you changes will be lost after you shut down KnowWE. To make the changes effective for the next restart, you have to perform Maven Install on KnowWE-App.

Create a second runtime configuration for building KnowWE, just like shown here: [http://d3webwiki.informatik.uni-wuerzburg.de/Wiki.jsp?page=Workspace#section-Workspace-CreateARunConfigurationForBuildingTheWiki], just check the "Offline" checkbox. __Note__: Do not enable this option for your regular build, only use it if Artifactory is down or you are not connected to the internet!

! INFO: ERROR: Failed to create a Wiki engine: JSPWiki: Unable to load and setup properties from jspwiki.properties.
At line 170 added one line
This is a missleading message display caused by unprecise error handling within jspwiki initialization code. The try-catch does not only include reading of the jspwiki.properties file, but also initialization of plugins/filters, i.e. also entire initialisiation of KnowWE. If you have recently changed code of KnowWE or a KnowWE-Plugin this error __most likely__ has __nothing__ to do with the jspwiki.properties file. It can be any kind of exception happening during KnowWE initialization. After the ''Unable to load and setup properties from jspwiki.properties'' the ''e.getMessage()'' of the actual exception is shown (without stack-trace unfortunately). __Tipp:__ Check the message string to guess what kind of exception it might have been; Consider your latest code changes; if nothing helps start debugging, e.g. in ''Environment.initInstance()''

! Are d3web's Session objects thread-safe for multi-threaded environments?
At line 175 added one line
In general a single d3web session is not thread-safe for write access. Reading contents from the same session with multiple threads is ok. But having an applications where multiple threads simultaneously read/write to a session, they need to be synchronized. Even if there is only one thread that writes to the session, it need to be synchronized with all reading threads. By convention, in d3web this should be done using the "Session"-Object as the semaphore for synchronization. This makes sure that your code will be interoperable with all other applications code (also considering this convention), without being in danger to create deadlocks.
