Pact-jvm: XmlBodyMatcher: Reading text values that cointan special characters from elements fails with pact-jvm-provider-junit version 4.0.2

[vasile21]

_Description:_
We have pact-jvm-provider-junit_2.12 with version 3.6.14 and we used XmlBodyMatcher to match response values in our provider side and all the rules passed smothly :)
We tried to updated to pact-jvm-provider-junit (version 4.0.2) and we noticed that rules for fields that contained special characters like: ("[", "!", "*","]") fail to pass anymore.
_Example:_

• provider response:

 <?xml version="1.0" encoding="UTF-8"?>
 <providerService version="1.0">
   <attribute1>
     <newattribute>
         <date month="11" year="2019"/>
       <name><![CDATA[Surname Name]]></name>
     </newattribute>
     <newattribute2>
       <countryCode>RO</countryCode>
       <hiddenData>ABCD***************010101</hiddenData>
     </newattribute2>
   </attribute1>
 </providerService>

• defined pact rules:

"$.providerService.attribute1.newattribute.name":{
 "matchers": [
     {
     "match": "equality"
     }
     ],
     "combine": "AND"
     },
 },
 "$.body.providerService.attribute1.newattribute2.hiddenData": {
     "matchers": [
     {
       "match": "equality"
     }
   ],
   "combine": "AND"
  }

Error message:

java.lang.AssertionError: 
0 - BodyComparisonResult(mismatches={$.providerService.attribute1.newattribute.name=[BodyMismatch(expected=[name: null], actual=[name: null], mismatch=Expected [name: null] to equal [name: null], 
path=$.providerService.attribute1.newattribute.name, diff=null)],
 $."$.body.providerService.attribute1.newattribute2.hiddenData=[BodyMismatch(expected=[hiddenData: null], actual=[hiddenData: null], mismatch=Expected [hiddenData: null] to equal [hiddenData: null],
path=$.body.providerService.attribute1.newattribute2.hiddenData, diff=null)]}, diff=[- <?xml version="1.0" encoding="UTF-8"?><providerService version="1.0"><attribute1><newattribute><date month="11" year="2019"/><name><![CDATA[Surname Name]]></name></newattribute><newattribute2>

Instead of match: equality I also tried with regex
"match": "regex", "regex": "^.ABCD*[\\*]{15}010101.*$"
but I received same error message
