> Version jcs-3.1 introduced an option to use EncryptingSerializer instead of StandardSerializer.
> However when EncryptingSerializer  is configured for LTCP by :
> jcs.auxiliary.LTCP.serializer=org.apache.commons.jcs3.utils.serialization.EncryptingSerializer
> UDPDiscoveryReceiver throws an error when trying to serialize received message ( error bellow).
>  
> Root cause of this error:
> calling deSerialize method in line 265 :
> serializer.deSerialize(byteBuffer.array(), null);
> byteBuffer.array() - returns byte[] which size is the full capacity of ByteBuffer not the size of recived message.
