Improve wildcard support for the key attribute in the roles access
match element and whitelist entry element, allowing prefix match for
the mBean properties.
The parameter failoverOnInitialConnection wouldn't seem to be used and
makes no sense any more, because the connectors are retried in a loop.
So someone can just add the backup in the initial connection.
In LargeMessageImpl.copy(long) it need to open the underlying
file in order to read and copy bytes into the new copied message.
However there is a chance that another thread can come in and close
the file in the middle, making the copy failed
with "channel is null" error.
This is happening in cases where a large message is sent to a jms
topic (multicast address). During delivery it to multiple
subscribers, some consumer is doing delivery and closed the
underlying file after. Some other consumer is rolling back
the messages and eventually move it to DLQ (which will call
the above copy method). So there is a chance this bug being hit on.
The crititical analyser trigger the broker shutdown if try to
removeAllMessages with a huge queue. The iterQueue is split so as
not to keep the lock too time.
The LocalMonitor tick log is very useful to establish a "heartbeat" log
statement. It is moved into its own logger from PagingManager logger,
which is too verbose to leave activated indefinitely in production.
This is needed to aid some lift and shift migration from activemq5 where non-java clients have support for older openwire protocols.

When CoreMessage is doing copyHeadersAndProperties() it doesn't
make a full copy of its properties (a TypedProperties object).
It will cause problem when multiple threads/parties are modifying the
properties of the copied messages from the same message.
This will be particular bad if the message is a large message
where moveHeadersAndProperties is being used.
It use RandomAccessFile to allow using heap buffers without additional
copies and/or leaks of direct buffers, as performed by FileChannel JDK
implementation (see https://bugs.openjdk.java.net/browse/JDK-8147468)
