Here's my test bed:
run the unit test:
org.apache.uima.ruta.engine.StackedScriptsTest
There should be some logging output like the following.
There is a log for the first RutaBasic (begin/end/addr) and for the
content of one of its fields (beginMap), for the begin of the process
method and after the basics are initialized (when the information is
recreated/the map (actually arrays) are filled again).
