[MINA 1.x] Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: edu/emory/mathcs/backport/java/util/concurrent/Executor

Hello,
I'm very confusing. The first time I try to run the application from
mina 0.8.x to 1.x. The exception below is occurred. 
Could you please help me to solve the problem? Thank you so much.

Posted by Jeroen Brattinga <je...@gmail.com>.

For Mina 1.x you'll need the concurrent backport library (
http://dcl.mathcs.emory.edu/util/backport-util-concurrent/). Or -if your
target platform is Java 1.5 and higer- you could change all
edu.emory.mathcs.backport.java.util.concurrent references to
java.util.concurrent (see another post in this mailing list for a simple
find/replace action).
