+
+	* src/main/java/de/intevation/gnv/utils/ExclusiveExec.java: New. This class
+	  can be used to synchronize threads with a given key. To use this
+	  synchronization, you just have to do something like the following:
+		  UniqueKey token = ExclusiveExec.INSTANCE.acquire(key);
+		  // your code to be synchronized
+		  ExclusiveExec.INSTANCE.release(token);
+	  A thread needs to wait if there is already a thread with the given key 
+	  which has acquired a token. Threads with a different key don't need to 
+	  wait for this thread.
+
+	* src/main/java/de/intevation/gnv/state/profile/horizontalcrosssection/HorizontalCrossSectionMeshOutputState.java:
+	  Synchronize shapefile writing of artifacts which have the same uuid.
+
+	* src/main/java/de/intevation/gnv/utils/FileUtils.java: Added a function to
+	  delete the content of a directory.
