Fork=1 actually looks fine, should just not be 0.

Looks like I'm violating assumptions of source deployment on travis somewhere. Will be offline for a few days and look at it afterwards. |
The compilation of branch aggregated-java-sources (you know, the one that allows to compile without bootstrap lib, e.g. for Gentoo) failed because https://repo.maven.apache.org/maven2/org/openjdk/jmh/jmh-generator-annproces-1.22.jar was not found. |

Start work on a benchmark suite for JFlex (addressing #698).
Initial numbers indicate that we do have a CPU performance regression from #697 (two-level cmap) of ~18% in the scanning engine with a scanner that has almost no actions. Needs more investigation, but it might mean that we should offer this as an option in addition to the old one-level cmap. The new setup is actually faster on a single cold-start run on small to medium inputs, probably because the one-off cost of initialising the cmap array is high in the old version.
