What's new in JPPF 2.3:

October 19th, 2010

Changes:
· JPPF now takes advantage of computers on which no user activity is occurring. It is very easy to configure a JPPF node to start when no keyboard or mouse activity has occurred for a specified time, and stop upon any new activity from the user.
· The scheduling mechanism has been improved to provide more fairness among concurrent jobs with the same priority.
· Logging traces are now available as JMX notifications via the JPPF management APIs. Developers can now receive, display and store traces from nodes and servers in a single location.
· A long-awaited new mechanism enables the detection of hardware failures of a node or server, allowing recovery in a resonable time frame. This brings a new level of resilience and reliability to the JPPF grid.
· It is now possible to configure a node to run in the same JVM as a JPPF server, via a single on/off switch.

New Features:
· 3059420 - Take advantage of idle computers
· 3044110 - Job scheduling enhancements
· 3042238 - JMX-based remote loggers
· 3042227 - Provide packaged sources for each module
· 2981736 - Pluggable panels in the administration UI
· 2977887 - Ability to run a node in the same JVM as the server

Bug Fixes:
· 3074513 - ClassCastException using JPPFClient(String) constructor
· 3071454 - OOME: Direct buffer space, reading large data from a socket
· 3071045 - Uncaught OOM in the driver while receiving tasks from a node
· 3069849 - Driver hangs on disk overflow operation
· 3066604 - Nodes shown in red in the console after driver restart
