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>
</amq:filteredKahaDB>
</amq:filteredPersistenceAdapters>
</amq:mKahaDB>
</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.
