-------------------------------
Summary: Corrupt KahaDB Journal may cause EOFException at Broker
startup
Key: AMQ-4339
URL: https://issues.apache.org/jira/browse/AMQ-4339
Project: ActiveMQ
Issue Type: Bug
Components: Message Store
Affects Versions: 5.8.0
Environment: Java 1.6.0 most releases, tested on lots of different
hardware, tested on Linux distros only.
Reporter: Ken Barber
During the occasional KahaDB journal corruption, ActiveMQ may receive an
EOFException. The easiest way to replicate this for us has been to purposely
put junk into a journal as so:
echo "asdf" > db-1.log
The exception in this case has been (this error is specific to AMQ 5.6.0, so
lines may mismatch on 5.8.0):

What is strange about this problem, is that upon a restart of the broker the
journal is 'reset' it would seem and things go fine afterwards.
