standalone@localhost:9990 /] echo-dmr /system-property=test30:add(value='my test')

{
"address" => [("system-property" => "test30")],
"operation" => "add",
"value" => "'my test'",
"operation-headers" =>

{"GIT_MESSAGE" => "monmessage"}

}
We have monmessage instead of mon message
Setting ignoreWhitespace to false in HeaderValueState fixes this but doesn't trim the result even if we are quoting (single or double) the value.

[standalone@localhost:9990 /] echo-dmr /system-property=test30:add(value='my test')

{GIT_MESSAGE="mon message" ; header2=test}

The closing '"' is missing.
