On second note, I made ArrayBoundsCheck run for all reachable methods, as a whole-program transformation. Maybe a config option should be added incase someone wants to run the transformation only on application classes? |

This fixes #1354. It's caused by the fact that multiple running ArrayBoundsChecker transformations can run certain analyses (SimpleLocalDefs) on the same method, resulting into data being overwritten (in this case, the local.getNumber field). I suspect this happened, because the transformation was designed before (2000) Soot parallelized BodyTransformation's or even supported SceneTransformation's.
I'm not sure if I modified all the documentation correctly. GitHub pages still needs to be modified I think. Furthermore, I added a -w flag to the annot-arraybounds, since now its a whole-program transformation. As for the ui code (PhaseOptionsDialog) I didn't test it.
I've tested the transformation and it works in whole-program mode. Hope this is of any use.
