Upgrade to 6.4 Breaks Custom Branding

Has anyone noticed any issues with upgrading to AA 6.4 breaking custom branding?  I just upgraded a 6.3.7 system to 6.4 and the logo used on the enrollment portal and auth request screens doesn't appear anymore.  I tried building a new custom branding JAR, but no matter what I do, the graphics do not appear.  These are the two settings:

OIDPENDUSER.AuthProductImage=

OIDPENDUSER.LoginProductImage=
