ClassCircularityError when using LdapLoginModule

I disabled the SimpleLoginModule in repository.xml and configured a 
login.conf file with the com.sun.security.auth.module.LdapLoginModule 
(from JDK 6).  After creating LDAP users for the admin & anonymous 
identities, Sling starts up fine.

However, when requesting a node with a JSP rendering script, the 
JspScriptEngineFactory throws an ClassCircularityError on activate - it 
seems to be looping in the RepositoryClassLoader as it tries to login to 
the repository (stack trace is below):
