+	Another attempt to fix gnv/issue34
+
+	* src/main/java/de/intevation/gnv/geobackend/base/DefaultResultDescriptor.java:
+	  Add a toString() method.
+
+	* src/main/java/de/intevation/gnv/geobackend/sde/datasources/ArcSDEConnection.java:
+	  Added an idle time detection mechanism. You can call touch() on
+	  a connection to refresh the internal timestamp and ask with isActive()
+	  if a constructor given time interval in milliseconds is exceeded.
+
+	* src/main/java/de/intevation/gnv/geobackend/sde/connectionpool/ArcSDEPoolableObjectFactory.java:
+	  Added a check of inactivity to validateObject() before relying on SDE logic.
+	  This is the last line of defence if the testServer() call is going not to respond.
+	  This duplicates the eviction policy of Apache Commons pool a bit but I found
+	  this way to be more trustworthy.
+
+	  The idle time is configure with the property 'serverInactiveInterval'.
+	  units: seconds. Defaults to 5 minutes.
+
+	  The unit of 'serverRoundtripInterval' (parameter of testServer()) is now
+	  in seconds, too. Default: 5 seconds. This is the value used in GeoTools.
