Now I understand the situation.  You still had some old log files with 
formal content, whose format I've changed again in the meantime. There was 
already some protection against such bad log files, but I did not handle 
all possible exceptions (due to the general confusion about exceptions on 
the JVM).

This should be more robust in Isabelle/d8ca566b22b3.
