Erro: Axis2 + JDK 1.6

[santoro]

Tenho um webservice que funciona normalmente com o java 1.5 porém com o java 1.6 dá o seguinte erro:

Exception in thread “main” javax.xml.stream.FactoryConfigurationError: Provider javax.xml.stream.XMLInputFactory could not be instantiated: java.lang.InstantiationException

Alguém tem idéia de qual seria o problema?
