"C:\Program Files\MATLAB\R2017b\bin\matlab" -nodesktop -nosplash -wait -log -minimize -r "matlab.addons.toolbox.installedToolboxes();"
When I execute the above command I get this exception:
Error using matlab.addons.toolbox.installedToolboxes
Java exception occurred:
java.lang.UnsupportedOperationException: The first invocation of this method cannot be on the MATLAB thread.

This seems to only happen with 2017b, I have tested the same with 2016a 2016b and 2017a without problems
