Description

I got an ArrayIndexOutOfBoundsException while doing some heavy XAR importing (and there might have been more than one import running in parallel by accident).

It looks very similar to https://bugs.java.com/bugdatabase/view_bug.do?bug_id=6231579 i.e. incorrectly using a java.text.SimpleDateFormat from multiple threads without synchronization in com.xpn.xwiki.objects.DateProperty.toText().

Here is the backtrace:
