[jira] [Updated] (AMQ-3396) ActiveMQ fails to restart when there is
a zero broker sequence ID
[ https://issues.apache.org/jira/browse/AMQ-3396?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Michael Alford updated AMQ-3396:
--------------------------------
Description:
ActiveMQ broker server fails to start as a Windows Service.
A NullPointerException happens during startup and then ActiveMQ shuts down automatically.
Only workaround discovered so far is to drop all the database tables before starting up the server.
{code:title=JDBCPersistenceAdapter.java}
public long getLastMessageBrokerSequenceId() throws IOException {
TransactionContext c = getTransactionContext();
try {
long seq = getAdapter().doGetLastMessageStoreSequenceId(c);
sequenceGenerator.setLastSequenceId(seq);
long brokerSeq = 0;
if (seq != 0) {
byte[] msg = getAdapter().doGetMessageById(c, seq);
if (msg != null) {
Message last = (Message)wireFormat.unmarshal(new ByteSequence(msg));
brokerSeq = last.getMessageId().getBrokerSequenceId();
} else {
LOG.warn("Broker sequence id wasn't recovered properly, possible duplicates!");
}
}
return brokerSeq;
} catch (SQLException e) {
JDBCPersistenceAdapter.log("JDBC Failure: ", e);
throw IOExceptionSupport.create("Failed to get last broker message id: " + e, e);
} finally {
c.close();
}
}
{code}
When the byte array "msg" is not null but is populated with zeros, the wireFormat unmarshal call will return null.
This then causes a NullPointerException on line 237 of JDBCPersiistenceAdapter.
