Here is the "xjc version" trace :
xjc version "hudson-jaxb-ri-2.1-2"
JavaTM Architecture for XML Binding(JAXB) Reference Implementation, (build hudso
XJC seems to use a 2.1 version of jaxb instead of 2.2
And here is the version declared into the JAXB libs :
jaxb-api.jar's MANIFEST.MF :
Specification-Title: Java Architecture for XML Binding
v2.1 instead of 2.2
jaxb-impl.jar's MANIFEST.MF :
v2.1.13 instead of 2.2.1
Thank you Martin to take care about my issue.
