I am trying to generate a news entry in a space using the SOAP API. Even if I specify a publishDate, the news is always published with the date at which I invoked the SOAP method:

Code to reproduce:

// Get the confluence service
ConfluenceSoapService confluenceService = getConfluenceService();
final String authToken = confluenceService.login(USERNAME, PASSWORD);

// Build the comment
RemoteBlogEntry news = new RemoteBlogEntry();
news.setContent("Fake news auto-generated by JUnit tests");

// Use another publish date
final Calendar publishDateCalendar = Calendar.getInstance();
publishDateCalendar.set(Calendar.YEAR, 2005);
publishDateCalendar.set(Calendar.MONTH, 6);
publishDateCalendar.set(Calendar.DAY_OF_MONTH, 24);
news.setPublishDate(publishDateCalendar);

news.setTitle("Fake news (JUnit test please ignore)");
news.setSpace("TEST");

// Publish the news
confluenceService.storeBlogEntry(authToken, news);

confluenceService.logout(authToken);

This is blocking the migration of our portal system to confluence ...
