      Under some conditions (that I'm failing to diagnose) Converter.canConvert(Class type) is being called with null as argument on a converter which is not NullConverter, those calls lead to {{NullPointerException}}s.

          Do you at least have stack traces?

          Yes:

          java.lang.NullPointerException
  at java.lang.Class.isAssignableFrom(Native Method)
  at com.thoughtworks.xstream.converters.reflection.ExternalizableConverter.canConvert(ExternalizableConverter.java:73)
  at com.thoughtworks.xstream.core.DefaultConverterLookup.registerConverter(DefaultConverterLookup.java:74)
  at com.thoughtworks.xstream.XStream$2.registerConverter(XStream.java:502)
  ...

          This is after a XStream constructor call, in one of the registerConverter call in the construction chain.
