[rules-users] dialect: Java or MVEL

[Mark Proctor]

Java is more mature in tooling and implementation and is still currently 
the default implementation and the recommended one if you are not sure. 
MVEL will eventually become the default dialect when it matures, its 
advantage is in the simpler language it provides, which helps make rules 
easier to read and write. It can also operate in reflection mode, which 
can really help for large rule based systems that have perm gen issues.
