Infinite loop when there are no results using JSON output

andras_kerekes — Thu, 09 May 2013 19:26:24 GMT

I am using Splunk 5.0.2 with Java SDK 1.1. If I run a search that does not return any result, and use the ResultReaderJson class to parse the result the com.splunk.ResultsReaderJson#readEvent method gets into an infinite loop and does not return.

The problem is that when Splunk tries to parse the following:

{"results":[{"count":0}]}

It starts reading the object starting at the {, it reads the count as name (in /com/splunk/ResultsReaderJson.java:287) then the next Json token is a JsonToken.NUMBER with the value 0, but the method does not handle it, it expects only *_START/ *_END, NAME and STRING tokens.

Upgrading to Splunk 5.0.3 resolves the problem as it returns an empty array for results:
"results":[]

The ResultReaderJson then can correctly parse it.
