[rules-users] Cannot instantiate PackageBuilder object

[Edson Tirelli]

   All the spreadsheet compiler does is to convert your XLS into a DRL
source code. The actual "code compiler" is the PackageBuilder. It usually
fails like that if you are missing either JDT / Janino compiler (whichever
you are using for java dialect) or MVEL (for MVEL dialect).
