When you encounter such cases, please log a JIRA at:
https://issues.apache.org/jira/browse/CXF
Most of the time, we can just add an NPE guard or something there to produce
a better error message. For invalid XML, we sometimes have issues trying to
detect that depending on the error messages that the parser provides, but if
there is a JIRA (with preferably a test case), we can at least look and try.
