Possible JVM issue with "missing" filter

(Apologies in advance for including sample code - having issues with gist
at the second...)

When running some tests against ElasticSearch 1.3.2, we noticed what
appears to be a problem with the "missing" filter. This problem manifests
with JVM 1.7.0_60 (recommended in the ES documentation), but disappears
under JVM 1.7.0_67.

If we create a simple template with a single property designating a string
field:

{
"template": "empty_ex*",
"settings": { "number_of_shards": 1 },

"mappings": {
    "empty_example": {
       "_source": { "enabled" : true },
        "properties": {
            "testField": { "type": "string" }
        }
    }
}

}

And then enter a simple document:

curl -XPUT http://localhost:9200/empty_ex1/empty_example/1 -d
'{"testField":""}'

Then the following simple filter fails to retrieve the document in JVM
1.7.0_60, but retrieves the document properly in 1.7.0_67.

{
"filter": {
"missing": {
"field": "testField"
}
}
}

Simply switching out the JVM changes the query results on existing indexes,
so this appears to be a query-side issue only. Adding "null_value": true
does not return any hits under JVM _60 either...

Can someone confirm this?

I can not reproduce this on Mac OS X.

The behavior of "missing"/"exists" filter for empty fields has slightly
changed, see Speed up `exists` and `missing` filters on high-cardinality fields · Issue #5659 · elastic/elasticsearch · GitHub

Thanks. Search result changed since 1.24 (current 1.3.2) · Issue #7348 · elastic/elasticsearch · GitHub is a
recently opened bug that addresses my problem. Don't know why 1.7.0_67
"fixes" it on my Linux box (and others who have replicated it...)
