IllegalArgumentException: Reverse paths are not allowed (containing a . or ..), use getParent(): WEB-INF/wsdl//imported/my-service/1.0-SNAPSHOT/../../../common/1.0-SNAPSHOT/CoreComponentTypes.xsd

To be lees strict, this should be valid

vf.findChild("foo/bar/../file.txt")

and this not

vf.findChild("foo/bar/../../../file.txt")
