Screenshot of debug showing null variable in stack

The MapViewLogger class consistently throws Exceptions on Win7 x86_64 with STEM 2.0.2 and STEM 2.0.1. This particular logger will not record any screenshots of an otherwise operable simulation.

This occurs under the STEM Release Version, the STEM Latest Build, and a STEM Custom Build in Both Eclipse 4.4.0 RCP Luna as well as in a STEM Custom Build on Eclipse 3.8 Juno.

ENVIRONMENT:

The problem can be reproduced with JRE1.6, JRE1.7, and JRE1.8 (for pre-built installs) and JRE1.6 (for custom builds).  

All tests were done on Windows 7 x86_64 with 8GB RAM.  Memory to STEM was also increased to 2GB wit no effect.

What is curious is that the other Map Loggers (and CSV loggers) work just fine:

-*Map View Logger :: FAILS*
-Equirectangular Map Logger :: Success
-Mercator Map Logger :: Success
-Orthographic Map Logger :: Success
-Azimuth Map Logger :: Not Tested
-CSV File Logger :: Success


PROCEDURE:

1. Added Map View Image Logger to a working and tested scenario (with working CSV logger).  Selected File / Save All.  Selected Window / Reset Perspective.

2. Right clicked Simulation in Designer / Selected Run.  Simulation runs.

3. Pause simulation and check console.  Exceptions are visible.   but Map View Logger is failing to console with repeating Exceptions (once per simulation cycle).

4. Ensured Map View window is open and selected.  Opened it again with no effect.

5. Other Map loggers work fine. CSV Logger is logging to the default workspace Record directories correctly.

COMMENTS:

Two clues here:

(1) MapViewImageWriterLoggerImpl.java:245 seems to be failing.  When view = getMapViewFromWorkbench(); gets called, the object view is null even after the call to getMapViewFromWorkbench().

(2) In the same file, on line 338 , when GeographicControl control = getMapControlForSimulation();  is called,  control is also coming back with a null value.
