Component: Maven Eclipse Plugin

Steps to reproduce the issue:
This assumes you have already added the "Test" file for the sub-process in question. Please refer "Adding Unit Tests Assertions" section from https://github.com/TIBCOSoftware/bw6-plugin-maven/wiki/UnitTesting to add test file.
This assumes the test project is Mavenized.

Direct subprocess has a mapper activity which concats test data to input string.

1. Run "mvn clean initialize site package" in parent project: "payee-service-parent"
2. Assertion error @Mapper in test case "/PayeeAppModule/Tests/SubProcess.bwt":
   
   

See the output text formatted below:
[ERROR] -----------------------------------------------------Fault Data---------------------------------------------------------------------
Assertion Failed For Activity with name [Mapper] in Sub-Process [com.tecxis.payee.mapping.SubProcess] for TestCase File [/PayeeAppModule/Tests/SubProcess.bwt] [Reason] - Validation failed against Gold file. Please compare Activity output against Gold output values [Activity Output:
<tns:Output xmlns:tns="http://www.tibco.com/namespaces/tnt/plugins/generalactivities/mapper/1624722597444">â?¬ABC</tns:Output>]
[Gold Output: <tns:Output xmlns:tns="http://www.tibco.com/namespaces/tnt/plugins/generalactivities/mapper/1624722597444">â?¬ABC</tns:Output>]
3. Activity output matches the Gold output however assertion fails.

Additional information you deem important (e.g. issue happens only occasionally):
€ symbol is escaped as non-XML characters: "â?¬"
