In fact I use the following to not have update date automatically set when
saving document:
doc.setContentDirty(false);
doc.setMetaDataDirty(false);
This is not available from Document but from XWikiDocument, that's why I
use XWiki#getXWiki#saveDocument.
This is old code. I realize now that maybe I could just update underlying
XWikiDocument returned by Document#getDoc, then use Document#saveDocument
to save it ?

In fact currently in the component called from my job, I use the following
to retrieve context and xwiki old-core api, in initialize():
ExecutionContext context = execution.getContext();
this.context = (XWikiContext) context.getProperty("xwikicontext");
this.xwiki = this.context.getWiki();
Only Execution is @Injected.
I'll try to get XWikiContext injected as you propose.
Thanks !
