IndexOutOfBoundsException on DB.commit() #1043

We've been using MapDB on our application for years now without any issue. Now we are on version 3.0.10. But yesterday we got this exception when committing an update:

java.lang.IndexOutOfBoundsException: Index: 1, Size: 1
        at java.util.ArrayList.rangeCheck(ArrayList.java:659)
        at java.util.ArrayList.get(ArrayList.java:435)

        ...

After that, some calls were ok while others gave similar errors both updating and getting data. We had to restore a backup from the day before. Any idea on what could have caused this error?
