Problem does not ocurre with JDK 6 (jdk1.6.0_45) or JDK 7 (jdk1.7.0_25). IMHO this used to work with older versions of Java5.

Caused by: javax.xml.stream.XMLStreamException: Precondition for readText is nextEvent().getTypeEventType() == START_ELEMENT (got 4) at com.bea.xml.stream.XMLEventReaderBase.getElementText(XMLEventReaderBase.java:87)

This (com.bea) might indicate that there was some merge with JRockit into Tiger(java5) during maintenance release. Support on Java5 has reached EOL in October 2009, latest 1.5 release was u45. I should try to get this and run the tests again. If it is working then, we are done. Otherwise this remains a 1.5 bug and we will set to wontfix as there is nothing we can do about it.

jdk1.5.0_22 is the latest tiger release that I can get for free. Hence there is nothing left that I can do about this problem.

I just noticed that this problem only occurs when the tests are executed via surefire in maven. There is no such problem if I invoke the test manually or via Eclipse. So it seems that maven is not properly shading the classpath during surefire testing and maven itself may have a different StAX implementation that behaves uncommon. For our project I consider this as not a bug (invalid).
