Looks like a bug in Drools itself.
Try upgrading to CR1 and create a JIRA:
https://issues.jboss.org/browse/DROOLS
Would be nice if you can find a consistent way to reproduce it
(presuming it's not a race condition).

Hi,
I am using planner 6.0.0.beta5. to schedule some kind of
events like in curriculum example, and created web front
end for this using Vaadin.
but for some reason some users (only few) from this web
client get this exception (at the end) and scheduler
fails.
What could have been the cause for this? the code I have is
as follows.
SolverFactory solverFactory = new XmlSolverFactory(
"/org/optaplanner/examples/curriculumcourse/solver/curriculumCourseSolverConfig.xml");
TerminationConfig tc =
solverFactory.getSolverConfig().getTerminationConfig();
tc.setMaximumSecondsSpend(120L);
Solver solver = solverFactory.buildSolver();
creating the solver is throwing the exception.
log:
