summary: Merge

which apparently broke earley boyer - this is a merge from 9.
It has been broken since, and it is extremely strange that no harness has picked it up.

To reproduce, from the make directory:

alhazred:make marcus$ sh ../bin/runopt.sh -scripting ../test/script/basic/run-octane.js -- earley-boyer --verbose --iterations 2
[earley-boyer] loading 'earley-boyer' [earley-boyer.js]...
[earley-boyer] running 'earley-boyer' for 2 iterations of no less than 5 seconds
[earley-boyer] *** Aborted and setting score to zero. Reason: java.lang.AssertionError

The assertion is

        assert optimismInfo == oldOptimismInfo;


Not sure if it's a valid assert or not.
