Similarity score NaN when comparing two exact similar jsons containing empty array

[aymar99]

Steps to reproduce :

• Use 0.0.8 version of the library.

• Use

new LenientJsonArrayPartialMatcher(), // comparing array using lenient mode (ignore array order and extra items)
new LenientJsonObjectPartialMatcher(), // comparing object using lenient mode (ignoring extra properties)
new LenientNumberPrimitivePartialMatcher(new StrictPrimitivePartialMatcher()) // comparing primitive types and manage numbers (100.00 == 100)
);

Pass the below json for both expected and actual,

{ "a":[] }

Print the similarity score, expected 100, actual NaN

I feel this method is where the fix is required,

json-diff/src/main/java/com/deblock/jsondiff/diff/JsonArrayDiff.java

Line 39 in 9dfab1e

return totalSimilarityRate / totalArraySize;

When the array size is zero, here there could be 0/0 error.

Hi,

Thanks for this feedback.
It's fixed in 0.0.9 version.
