[jira] [Commented] (OPENNLP-798) Division by Zero exception in the EvalParameters.

["Bruno P. Kinoshita (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OPENNLP-798?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14924188#comment-14924188 ] 

Bruno P. Kinoshita commented on OPENNLP-798:
--------------------------------------------

When I had a look at the _EvalParameters(Context[] params, int numOutcomes)_ constructor, and the subsequent code called in _EvalParameters(Context[] params, double correctionParam, double correctionConstant, int numOutcomes)_, where you have:

{noformat}
this.constantInverse = 1.0 / correctionConstant
{noformat}

I thought it could rise a division by zero exception. However, upon a closer look, I realised it was a double division, which will result in Infinity.

Joern, I think this issue can be closed as cannot reproduce, unless Gustavo has an exception trace or some sample code to reproduce it.
