Publication job scheduled for 1 year from today is immediately executed and causes infinite loop

• start CMS quickstart war and login as admin
• browse to a document, e.g. articles/myarticles1
• in workflow menu bar, choose 'publication actions'
• choose 'schedule publication'
• in dialog, change year in date to "current year + 1" (e.g. 2010 -> 2011)
• click OK
• document status will change to Live immediately (INCORRECTLY)
• also, when taking document offline, document will be published again automatically (publish job fires in infinite loop)

In the console, the hipposched:trigger node shows the correct firetime. This might suggest a bug in quartz (not sure).
