infinite loop when trying to convert JSONX with extra comma

[skunkworker]

I was parsing a JSON document that had an extra comma, and when trying to clean it up it produced an infinite loop and threw a format error.

input = " {\"foo\":\"bar\",,}"
JSONX.convert(input)

throws

!! format error: object literal - expected colon (:) - rest is >>}<<
!! format error: string literal - expected opening quote (") - rest is >>}<<
!! format error: object literal - expected colon (:) - rest is >>}<<
!! format error: string literal - expected opening quote (") - rest is >>}<<

endlessly.

Thanks for trying and reporting. That's a bug.

Happens to me as well in SON.Parse for:
'{ "mock": "text",}'
