Axel Uhl 59cbdf1e15 bug5741: cache Class.forName results while reading all operations of one RabbitMQ message; 
This avoids thousands of expensive Class.forName calls. Now, the next
most expensive thing is reading the class descripors from the stream.

Axel Uhl 4f61f4c925 made loading persistent wind estimation models more resilient against DB race conditions during initialization; 
after seeing the following exception:

it seems that during replica initialization a DB dropping / clearing may race against the
loading of the models. The gridFs.find() method has listed a file which then doesn't exist when trying to
open it. This would break the entire replication initialization process, and the replica will not
become available. By catching and logging the exception and simply leaving the model empty,
the initial load can then take over, and all models should be fine.
