-----------------------------------
Got hit by NPE in 5.5.0, when ActiveMQ starts and kahadb is corrupt:

Line 795 in 5.5.0 version of org.apache.activemq.store.kahadb.MessageDatabase
was
{code}
if (!checkpointThread.isAlive()) {
{code}
and after commits for AMQ-3559 that code is now
{code}
if (checkpointThread != null && !checkpointThread.isAlive()) {
{code}
which should resolve the NPE in this case as well.
AMQ-3634 will help with handling the case of corrupt kahadb. In other words,
looking forward to 5.6.0 release.
> KahaDB NPE when loading data from previous versions
> ---------------------------------------------------
>
> Key: AMQ-3559
> URL: https://issues.apache.org/jira/browse/AMQ-3559
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker
> Affects Versions: 5.6.0
> Reporter: Timothy Bish
> Assignee: Timothy Bish
> Fix For: 5.6.0
>
>
> When loading a data directory containing KahaDB logs from previous versions a
> NPE exception can be encountered. The new Version in 5.6 is v4 however an if
> statement in the MessageDatabase still checks against a current of v3. Code
> needs to be updated to use the VERSION field to ensure its checking against
> the most current value.
