Cannot cast from [Long] to [long]. Painless script in query

[awatkins (Aaron Watkins)]

Getting error, "Cannot cast from [Long] to [long]" and have tried many many things to no avail.

The data to query against:

"Data": {
	"Number of Components": 3,
	"Number of Components Array": [
		{
			"Component": 1,
			"Number of Foos": 0,
			"Number of Foos Array": []
		},
		{
			"Component": 2,
			"Number of Foos": 0,
			"Number of Foos Array": []
		},
		{
			"Component": 3,
			"Number of Foos": 1,
			"Number of Foos Array": [
				{
				  "Foo State": "Bar",
				  "Foo Name Text": "Boogada Boogada"
				}
			]
		}
	]
}

The "Painless" script:

boolean retVal = false;
if (doc[\"Data.Number of Components\"].value > 0){
	Long[] numFoos = doc[\"Data.Number of Components Array.Number of Foos\"].values;
	for (def i = 0; i < numFoos.length; i++) {
		if (numFoos[i] > 0L) {
			ArrayList foosArray = doc[\"Data.Number of Components Array\"][i][\"Number of Foos Array\"].value;
			String fooText = foosArray[i][\"Foo Name Text\"].value;
			if(fooText.compareTo(\"Boogada Boogada\") == 0){ 
				retVal = true;
			}
		} 
	}
}
return retVal;

The error:

"caused_by": {
	"type": "script_exception",
	"reason": "compile error",
