I cannot reproduce this error. Can you specify the exact steps and the versions for OS / JVM?

[weishengshui]

JVM
[root@dev3 lib]# java -version
openjdk version "1.8.0_101"
OpenJDK Runtime Environment (build 1.8.0_101-b13)
OpenJDK Server VM (build 25.101-b13, mixed mode)

OS
[root@dev3 lib]# uname -a
Linux dev3 2.6.32-642.1.1.el6.i686 #1 SMP Tue May 31 20:41:01 UTC 2016 i686 i686 i386 GNU/Linux
[root@dev3 lib]# cat /proc/version
Linux version 2.6.32-642.1.1.el6.i686 (mockbuild@worker1.bsys.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC) ) #1 SMP Tue May 31 20:41:01 UTC 2016
[root@dev3 lib]# cat /etc/redhat-release
CentOS release 6.8 (Final)

bug重现步骤：
[root@dev3 ~]#wget https://github.com/yahoo/pulsar/releases/download/v1.14/pulsar-1.14-bin.tar.gz
[root@dev3 ~]#tar -zvxf pulsar-1.14-bin.tar.gz
[root@dev3 ~]#cd pulsar-1.14-bin
[root@dev3 pulsar-1.14-bin]#./bin/pulsar standalone

It might be related openjdk vs oraclejdk. In any case in BookKeeper.getDefaultEventLoopGroup we should be really catching the NoClassDefFoundError and fallback to the NIO event loop.

Committed a fix in bookkeeper branch at YahooArchive/bookkeeper@8982635

Will close this issues when updating BK version here
