The epics team is pleased to announce the Java Channel Access 2.3.1 release! 

http://jca.cosylab.com

JCA is an EPICS Channel Access library for Java. For more information 
concerning EPICS or Channel Access please refer to the <a 
href="http://www.aps.anl.gov/epics">EPICS Web pages</a> or read the <a 
href="http://www.aps.anl.gov/epics/modules/base/R3-14/4-docs/CAref.html">Channel 
Access manual (3.14)</a>. <p>This page does not provide any native JNI 
libraries used by JNI implemenation of JCA, they can be obtained from <a 
href="http://www.aps.anl.gov/xfd/SoftDist/swBCDA/jca/index.html">EPICS JCA 
page</a> or built from source distribution.</p> <p>In June 2004 CosyLab agreed 
to become the "official" maintainer of JCA.</p> 

Changes in this version include:

  Fixed bugs:

o QueuedEventDispatcher deadlock detection added (if queue is full and event 
  is generated by event dispatcher queue). 
o Clean implementation of JNI AttachCurrentThread/DeattachCurrentThread. 
  AttachCurrentThreadAsDaemon used instead of AttachCurrentThread (to let JVM 
  to exit if not using EPICS 3.14.9 or newer). JDK 1.4 or newer required by 
  AttachCurrentThreadAsDaemon. 
o JNIMonitor.removeMonitorListener() implementation did actually add a 
  monitor listener. Fixed. 
o JNIChannel.get() threw a NullPointerException if channel not connected. 
  Fixed to throw CAException. 

  Changes:

o Ported part of CAJ tests to test JCA.  

Have fun!
