2012-02-19 Version 2.4.8

#40: Make project available via Nexus OSS

2011-02-06 Version 2.2.3

#1: Enable overriding builder properties using environment variable and properties file.
#3: Add mapping from Builder bean setter names to Coherence system properties.
#5: Add JMX support.
#6: Tidy up builder.
#8: Look at why Coherence 3.5 reflection updater doesn’t work with integers (and so need to use strings).
#9: Add checks for incoming parameters for DefaultLocalProcessClusterMemberGroup constructor.
#11: Add support for more than one than one Extend proxy in a cluster member group containing dedicated Extend proxies.
#12: Add support for more than one than one Extend proxy in a cluster member group containing storage enabled Extend proxies.
#13: Fix startAndShutdownWithKnownRequiredJarBeingExcluded test so that it doesn’t use multicast (it does so because member group is shutdown and resets the system properties).
#15: Improve builder setBuilderProperties to take a string for a properties filename, this will avoid the API user having to worry about getResourceAsStream etc.
#16: Add getExtendPort method to builder to allow this to be used as the starting port for people to offset from it.

#29: Reflection based cluster member with fallback to default behaviour.
#32: Before starting to build the cluster group output exactly what the final group will contain.
#33: Add ‘fast-start’ override file that reduces delay time before creating cluster.
#34: Add build incident reporter.
#35: Add support for the properties utils to log at a particular level.
#36: Add builder style support to reflection delegating cluster member.
#37: Improve JavaDoc for usage of stop and sleep.
#38: JMX monitor member doesn’t start-up when an Extend proxy is also used - system property not cleared causing problem.
#41: Reset system properties after cluster is up.
