Eclipse Issue: framework.EquinoxConfiguration$1 cannot be cast to java.lang.String

I noticed this issue when my eclipse decided to hang when compiling to my web server and because i'm impatient and decided to force close, I was then receiving the following error java.lang.ClassCastException: org.eclipse.osgi.internal.framework.EquinoxConfiguration$1 cannot be cast to java.lang.String (I managed to get this error showing when I attempted to startup the application with the ./Applications/eclipse/eclipse --debug command

SOLUTION

Whilst understanding that there could be many reasons why this occurs, the following blog, Eclipse hangs at startup showing only the splash screen resolved all the issues thus far.

HOW TO provision AD group membership from OpenIDM

OpenIDMICFAD-connector

For what I see, there's not too many supportive documentations out there that will demonstrate how provision AD group membership with the ICF connector using OpenIDM. The use of the special ldapGroups attribute is not explained anywhere in the Integrators guides to to the date of this blog. This quick blog identifies the tasks required to provision AD group membership from OpenIDM to AD using the LDAP ICF connector. However this doesn't really explain what ldapGroups actually does and there's no real worked example of how to go from an Assignment to ldapGroups to an assigned group in AD. I wrote up a wiki article for my own reference: AD group memberships automatically to users This is just my view, others may disagree, but I think the implementation experience could be improved with some more documentation and a more detailed example here.
