New Revision: 1352575

URL: http://svn.apache.org/viewvc?rev=1352575&view=rev
Log:
Improved information logged when the method is unable to compute the 
approximate byte size of a cached object using serialization: instead of a 
useless stack trace it is returned an informative message with the name of the 
class that is not serializable; in case of null objects a message is also 
logged.
