OpenSAML user discussion

Hi - 
   I was running some tests and noticed that my SAML output was incorrect.  I 
was able to resolve my issue, but was curious as to why code execution 
continued in a error state.  
Checking the logs, I saw an error regarding the signature process in 
org.opensaml.xml.signature.Signer.signObject.  From looking at the source, I 
noticed this code just writes the error to the log instead of throwing an 
exception to the caller:

lines 77-79 of org.opensaml.xml.signature.Signer.signObject:
        } catch (XMLSecurityException e) {
            log.error("An error occured computing the digital signature", e);
        }

Is this behavior intentional?  It seems a bit odd to not alert the caller of 
a critical error...

Thanks!
Dave
