Patches The following patch can be applied to the Brahms Agent Environment version 1.2.7 on any of the supported platforms. Extract the zip file into the Brahms/Agent Environment directory. Patch 14 July 2008 - Fixed a possible NullPointerException in resetting an external agent when shutting down the virtual machine. - Fixed an issue in logging reporting failures via the agent monitor when no cause/exception is present. Now just using the message as the cause - Changed the checksum routines used in the VerifyChecksum and CopyFile activities for empty files, now returning the checksum value of 0 for an empty file. - Fixed the copy file activity to supporting copying of large files > 64MB. - Changed the virtual machine to no longer invoke the start/stop methods on an external agent if the external agent failed to initialize. - Updated the retract belief activities to now also allow for a 'fromActor' argument to be passed to retract a belief from an actor other than the actor performing the retractBelief activity. This allows for retraction of beliefs from data objects that do not have any behavior. BaseGroup and BaseClass include additional retractBelief and retractBeliefValue declarations. - Added the ability to set the network interface to use to join a multicast group; property name: multicast.interface. This can be a useful property on multihomed hosts with a firewall configured to permit multicasting only on a single interface. - Fixed the multicast tester to verify that the content of a received packet is indeed a string before extracting the value.

		Brahms Eclipse Composer Plug-in V1.0.12 In addition to the Brahms Composer you can now also download and install an Eclipse plug-in for Brahms.
