Shibboleth SVN ConfigurationResource problem

[Sean Mason]

Hello all,

I am currently looking at implementing the Shibboleth identity provider and I am having some trouble configuring shibboleth to pick up configuration objects from subversion as documented at: https://wiki.shibboleth.net/confluence/display/SHIB2/IdPProdConfigFiles

For example, for the AttributeResolver configuration in service.xml I have something like:

<srv:ConfigurationResource xsi:type="resource:SVNResource"
	repositoryURL="https://url.to/svn/resource"
	workingCopyDirectory="/home/idpuser/idp/svnconf"
	resourceFile="attribute-resolver.xml"
	username="user"
	password="password"
	revision="1450" 
/>

I receive "org.springframework.beans.factory.BeanCreationException: SVN resource definition attribute 'revision' contains an invalid number"

If I omit the 'revision' attribute, the configuration successfully fetches the latest revision, so I am quite certain the other attributes are configured correctly.  I have tried other revision numbers known to be valid, and some that weren't to the same result.

I have searched through the archives and haven't stumbled on anyone having a similar problem, so I must be doing something comically simple wrong.  Can anyone show me where I am going astray?
Thank you,
Sean.
