Hi Gary,
When i switch my broker from 5.8 to 5.10, everything seems to be normal and
works fine. But when I switch back from 5.10 to 5.8, I am seeing issues.
Below are the details of my configuration:
1. Using MultikahaDB.
Configuration:
* <amq:persistenceAdapter>
<amq:mKahaDB directory="/u/khandela/activemq/kahadb"
journalMaxFileLength="64mb">
<amq:filteredPersistenceAdapters>
<amq:filteredKahaDB queue="flow.>">
<amq:persistenceAdapter>
<amq:kahaDB/>
</amq:persistenceAdapter>
</amq:filteredKahaDB>
<amq:filteredKahaDB queue="gear.>">
<amq:persistenceAdapter>
<amq:kahaDB/>
</amq:persistenceAdapter>
</amq:filteredKahaDB>
<amq:filteredKahaDB>
<amq:persistenceAdapter>
<amq:kahaDB/>
</amq:persistenceAdapter>

Details of my test case:
Started broker with 5.8, stopped and started with 5.10 (works fine) but
again stopped and started broker with 5.8 (Not working). Please note that I
have tested this with two case: (i) clients are conencted (ii) clients are
not connected, and in both the cases the same issue observed.

We don't really do version downgrades on the store, going forward should
work fine, going backwards doesn't really make much sense and is not
supported.
