Instead of going directly into backup mode within the shared-store
live activation, we just change the HA-policy to slave and return
to the caller - ActiveMQServerImpl.internalStart().
The caller will then handle the backup activation as usual
in a separate thread, such that EmbeddedJMS.start() can return.
Also added a related integration test.
sendMessage() may throw ActiveMQException that causes CNFE
at the management client. Also it should check if headers
in the message is null (to prevent NPE).
The ActiveMQJAASSecurityManager class uses LoginContext to validate
users and roles. LoginContext loads LoginModule classes defined in
the configuration (login.config) using current thread's context
classloader.
Normally this wouldn't be a problem but when a caller thread comes
from JMX (for example a client calls QueueControl.sendMessage() via
JMX) the caller thread has a different context class loader.
This will cause the LoginContext to fail to load the LoginModule
class (e.g. PropertiesLoginModule) and the validation will fail
even if correct credentials are supplied.
Broker should support full qualified queue names (FQQN)
as well as bare queue names. This means when clients access
to a queue they have two equivalent ways to do so. One way
is by queue names and the other is by FQQN (i.e. address::qname)
names. Currently only receiving is supported.
AIOFileLockManager doesn't work on NFS-mounted share store directories.
Since the GFS2 bug https://bugzilla.redhat.com/show_bug.cgi?id=678585
has been fixed end of 2011, the class AIOFileLockManager is no longer needed and I have removed it.

Add tests for this management operation with both core and AMQP encoded
messages. Also fix a few problems with the implementation like not
checking the passed-in headers for null and not counting messages
properly.
When a replica attempts to connect to a live server using a group-name
and there are > 1 servers on the network using that group there is a
chance it will fail because it doesn't keep track of all of the
topology data it receives. This fix ensures that all the topology data
from the cluster tracked until it is used and fails at which point it
is discarded.
When populate-validated-user = true AMQP messages can cause exceptions.
This feature isn't particularly applicable to AMQP so this commit
eliminates the exception and leaves the AMQP messages untouched
even if populate-validated-user = true. In other words,
populate-validated-user + AMQP is not supported.
If broker fails to decode any packets from buffer, it should
treat it as a critical bug and disconnect immediately.
Currently broker only logs an error message.
The following changes are made to support Epoll.
Refactored SharedNioEventLoopGroup into renamed SharedEventLoopGroup to be generic (as so we can re-use for both Nio and Epoll)
Add support and toggles for Epoll in NettyAcceptor and NettyConnector (with fall back to NIO if cannot load Epoll)
Removal from code of PartialPooledByteBufAllocator, caused bad address when doing native, and no longer needed - see jira discussion
New Connector Properties:
useEpoll - toggles to use epoll or not, default true (but we failback to nio gracefully)
remotingThreads = same behaviour as nioRemotingThreads. Previous property is depreated.
useGlobalWorkerPool = same behaviour as useNioGlobalWorkerPool. Old property is deprecated.
New Acceptor Properties:
useEpoll - toggles to use epoll or not, default true (but we failback to nio gracefully)
useGlobalWorkerPool = same behaviour as useNioGlobalWorkerPool but for Epoll.
