-------------------------------------------
Summary: UDPDiscoveryReceiver with EncryptingSerializer fails
Key: JCS-230
URL: https://issues.apache.org/jira/browse/JCS-230
Project: Commons JCS
Issue Type: Bug
Components: TCP Lateral Cache
Affects Versions: jcs-3.1
Reporter: Dorota Oeknigk-Urbanska
Attachments: patch.diff
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.
