TestCreateBlogPostAction fails in San Francisco

So I'm trying to generate a Confluence-2.6-SNAPSHOT jar to build a plugin, but unfortunately, one unit test fails:

testBackDatedPostDates(com.atlassian.confluence.pages.actions.TestCreateBlogPostAction)

The strange thing is, though, that the 2.6 builds on BEAC are green. This is on a virgin checkout of the confluence_2_6_stable branch. I ran 'mvn test' and got this one failure. I reproduced the failure it on my local machine through the command-line, through IDEA and again on BDAC. The error, if you're interested:

junit.framework.AssertionFailedError: sun.util.calendar.ZoneInfo[id="Asia/Jerusalem",offset=7200000,dstSavings=3600000,useDaylight=true,
