[x3d-public] JSON encoding long line split in HelloWorldProgramOutput.java

[John Carlson]

I'm working on temporarily patching HelloWorldProgramOutput.json to make it
so I can create Java from it.  I  know how to patch the java (Don, see
below enclosed--previous message).  I am now trying to repair the JSON I
use to create it. Note that the Java I produce does not have two sets
of @value diffs, probably because the JSON parser:

import javax.json.JsonObject;

dropped one with the same property name, as previously discussed.  I
suggest passing your JSON through jsonlint and diff, as this command does:
$ jsonlint C:/x3d-code/
www.web3d.org/x3d/stylesheets/java/examples/HelloWorldProgramOutput.json |
diff - ../../../data/HelloWorldProgramOutput.json
[snipped output,  if you want evidence, mail me privately]

diff ../../../data/HelloWorldProgramOutput.json /c/x3d-code/
www.web3d.org/x3d/stylesheets/java/examples/HelloWorldProgramOutput.json
