I'm trying to upgrade from drools 5.2.0 to 5.3.0 and having some difficulties with the planner benchmark.

I'd like to make a set of move factories common to all local search solvers, by adding them to inheritedSolverBenchmark block. But it seems that the localSearch environment always requires a selector, so I can't specify the localSearch environment for the solverBenchmark's without providing a selector. Here's a piece of code that gives runtime error: http://paste.ubuntu.com/718806/

From the UpgradeFromPreviousVersionRecipe.txt:

Warning for *SolverBenchmarkConfig.xml:
If the <inheritedSolverBenchmark> contains a <selector>, <acceptor> or <forager>,
that can no longer be inherited individually. Copy the <selector>, <acceptor> or <forager> to every <solverBenchmark>.
Because a benchmark specific <localSearch> will not overwrite the inheriting <localSearch>,
but instead add an extra localSearch phase, which will result in 2 separate, sequential localSearch phases.

This is annoying indeed... but as we can now define multiple phases to be run sequentially for 1 solver, for example
<localSearch>20 minutes simulated annealing</localSearch>
<localSearch>10 minutes tabu search</localSearch>
I haven't see a good way yet on how to define inheriting that it works properly.
If you got an idea, open an issue (issues.jboss.org JBRULES) and clearly describe it there.

The error is:

Exception in thread "main" java.lang.IllegalArgumentException: A selector requires configuration, for example a moveFactoryClass.

--- Note ---

If I understood correcly, the following configuration from examination examples:

examinationStepLimitSolverBenchmarkConfig.xml

contains a bug, because it specifies a maximum step count for a general solver

<termination>

<maximumStepCount>70</maximumStepCount>

</termination>

This gave the following exception:

Exception in thread "main" java.lang.UnsupportedOperationException: StepCountTermination can only be used for phase termination.

Thanks for reporting this, I 'll fix it.

Thanks,
