I may be mistaken, but the stack trace looks as if a stateless
knowledge session is being run, wherein it executes a RHS
("employeePreloadSystemConstants") where some fact is being inserted.
Not sure what *ought* to happen in this case, though: I've been trying
to find this out ever since 5.1.x. A meagre "...do not support
iterative insertions..." is all there is to be read, but what does
this imply? Simply doesn't work in an unspecified way? May crash on
workdays...?? A "tut, tut" from the Drools Team ??? ;-)

Looks like an 'or' bug. Which is surprising, as we had
'or' bugs in 4.x, and
fixed a lot of them for 5.x.
Could you build and try 5.5.x here now, this is the branch for the 5.6
release:
https://github.com/droolsjbpm/drools/tree/5.5.x
If it's still not fixed, could you write an isolated test? Seems like you
only need one rule, and two or three facts to trigger it. Ideally please
re-use facts from the test classes already existing - details of how to
write tests, and submit as pull requests is here:
http://docs.jboss.org/drools/release/5.4.0.Final/droolsjbpm-introduction-...
If you can get us this test pull request asap (next few days), we'll fix and
get it into the 5.6 release. Otherwise you may have to wait some time for a
fix.
