              Apache Commons Exec 1.2 RELEASE NOTES

The Apache Commons Exec team is pleased to announce the Apache commons-exec-1.2 release!

Apache Commons Exec is a library to reliably execute external processes from within the JVM.

Feature and fix release. Requires a minimum of Java 1.3.

Changes in this version include:

New features:

o Set names for started threads.  Issue: EXEC-55. Thanks to Dominik Stadler. 

Fixed Bugs:

o Issue: EXEC-68. 
  Watchdog kills process immediately if timeout is too large. 
  Thanks to Joel McCance. 
  
o Issue: EXEC-57. 
  Applied the patch from Nickolay Martinov but the timeout disguises the fact that the process might be still running.
  Therefore added a sanity check in order to throw an exception if the timeout for join() was exceeded. 
  Thanks to Nickolay Martinov.
   
o Issue: EXEC-60. 
  Fixed deadlock by calling the timeout observers outside of the synchronized block thereby removing a prerequisite of a deadlock. 
  Also added a test case to demonstrate that this problem is fixed (which of course can not guarantee the absence of a dead lock). 
  Thanks to Peter Kofler.
   
o Issue: EXEC-52. 
  Tests fail on HP-UX, because it uses a different syntax for the ping command. 
  Thanks to Nickolay Martinov.
   
o Issue: EXEC-49. 
  "Write dead end" IOException when using Piped streams w/PumpStreamHandler.
  When encountering a PipedOutputStream we will automatically close it to avoid the exception.  
  Thanks to Kevin Telford. 
  
o Issue: EXEC-34. 
  Race condition prevent watchdog working using ExecuteStreamHandler.
  Patch submittd by Kristian Rosenvold. 
  Thanks to Marco Ferrante.
