From the email conversation with the Vadim Zalunin

1) Use JAVA 8

2) to download latest cramtools jar: wget 'https://github.com/enasequence/cramtools/blob/master/cramtools-3.0.jar?raw=true' -O cramtools-3.0.jar

3) to check version: java -jar cramtools-3.0.jar | grep Version

4) to check if the class is in the jar file: jar tf cramtools-3.0.jar | grep CountingOutputStream

With trying the above it worked for me.
