Caused by: java.lang.ClassNotFoundException: javassist.bytecode.ClassFile

Hi Pentaho Folks,

Last week when I executed ./workbench.sh on my Mac I've got this error:

Caused by: java.lang.ClassNotFoundException: javassist.bytecode.ClassFile

It also occurs in Linux Ubuntu.

MacBook-Air-de-Caio:schema-workbench caiomsouza$ ./workbench.sh

How to solve it:

I edited workbench.sh and add the line below:

CP="${CP}${PS}${MONDRIAN_HOME}/lib/javassist.jar"

I also put the javassist.jar on psw-ce-3.5.0/schema-workbench/lib

After that, It worked fine.

If you find a better way to solve it, please let me know it.
