I recently upgraded from 1.56 to 1.59 and my hundreds of well commented JSON parameter files now all fail on the first commented line. This is true for /* */ and // style comments.
The exception.what() string thrown by boost::property_tree::read_json(filename,propertyTree) is
filename.json(linenumber): expected key string.
As I remove comments from my test JSON file the line number advances to the next comment.
Any hints as to how to deal with this? Removing all my comments is not an option.
