unable to fix DB with Doctor (ArrayIndexOutOfBoundsException)

One of my databases has failed (suddenly we were not able to connect with it from Java /with other DBs connection works fine/ and it is also not possible to connect with it from ObjectDB Explorer). DB was used by ver 2.6.9_09.
I tried to fix it with ObjectDB Doctor (from ver. ver 2.6.9_09, but also from newest version 2.8.6), but even Doctor fails:

How can I fix my DB?

Build 2.8.6_04 includes a new version of the Doctor that can handle this specific issue.
