errors in compile.json while running qx serve stops compiling

[voger]

I tried adding a new environment entry in compile.json while the qx serve command was running. The file was saved without beeing syntactically correct. I got this exception

Writing application tinyclone
>>> Compiled 1 classes in 27.367s
Applications are made
(node:22802) UnhandledPromiseRejectionWarning: Error: Failed to load compile.json: SyntaxError: Unexpected token <"tinyclone.apiServer"> at 10:9
        "tinyclone.apiServer": "http://localhost:4000/api/"

and while the qx serve application didn't terminate, it stopped watching for changes and compiling, and doesn't serve any new changes of the code.

Hi, same problem with qx compile --watch

Just a little more details.

It seems that loadJsonAsync (qx.tool.utils.Json.js:138) correctly throw an error when there is a problem (with a try/catch block), however the call to loadJsonAsync are neither in a try/catch block or with a .catch function, for example in my case (compile watch) it is in qx.tool.cli.api.CompilerApi.js:62, i do not know if it is the same place for qx serve i didn't test it.

@johnspackman Can you have a look - you know the code best.
