Rest Assured Body handling ArrayList - rest-assured

Question

I has a response body like this
enter code here
{
"applicationName": "Service MyService",
"someData": [
{
"name": "check1",
"props": [
"AAaa"
]
},
{
"name": "check2",
"props": [
"BBbb",
"CCcc"
]
}
]
}
Now I can use the following code and the test passes.
given().log().all()
.accept(JSON).expect().statusCode(SC_OK)
.when().log().all()
.get(contextPath + "/test")
.then().log().all()
.body("someData.name",
IsCollectionWithSize.hasSize(2))
.body("someData.name",
allOf(hasItems("check1", "check2")))
.body("someData.findAll {it.name == 'check1'}.props",
IsCollectionWithSize.hasSize(1))
.body("healthReports.findAll {it.name == 'check2'}.props",
IsCollectionWithSize.hasSize(2)));
However if I then attempt to check the values in the props field it fails I think because a ArrayList is returned and the matchers are checking on String.
given().log().all()
.accept(JSON).expect().statusCode(SC_OK)
.when().log().all()
.get(contextPath + "/test")
.then().log().all()
.body("someData.name",
IsCollectionWithSize.hasSize(2))
.body("healthReports.findAll {it.name == 'check1'}.props",
IsCollectionContaining.hasItems(startsWith("AA")));
I'm not sure how from the findAll ...props I can check the contents of the ArrayList.
The error displayed is:
JSON path someData.findAll {it.name == 'check1'}.props doesn't match.
Expected: (a collection containing a string starting with "AA")
Actual: [[AAaa]]
Any idea's ?

The findall return an Array of Array containing one element which is AA (which is why you have [[AAaa]] instead of [AAaa].
You have to flatten or extract one level of array to solve the problem I think.
