Issue with bodyRegexRule

[gokcekoyun]

I have a response body like this:
{
"user" : [
{
"data" : {
"address" : {
"street" : "GIR",
"postcode" : "WC1"
},
"timeStamp" : "2016-12-03T12:56:30"
}
}
]
}
As part of "matchingRules" I'd like to add a bodyRegexRule which looks like this:
bodyRegexRule("user[].data.timeStamp", "")

But this fails to verify.

Whereas, if I have a bodyTypeRule like the following, it's fine:
bodyTypeRule("user[*].data.timeStamp")

The headerRegexRule seems to be working fine.
