[rules-users] 5.6.0.CR1 causes exceptions

[Jonathan Knehr]

Just upgraded to the release candidate. I was using my own version of 5.6 that I had compiled a few months ago and everything was working fine.

Almost every single rule file now throws this exception when it gets added to the knowledge base.
