osx .observe(1) getsRuntimeError ( maximum recursion depth exceeded (Java StackOverflowError) )

[Joe White]

This works on the same Mac OS 10.11.6 system with SikuliX 1.1.0.
Running the same program attached give a Java StackOverflowError on
the line "sample.observe(1) # observing for 1 seconds (script pauses here - Java Stack Overflow)
It happens the very first observation.....same JDK and java versions.
