[rules-users] bytecode representation of rules

[Edson Tirelli]

   Take a look at the org.drools.rule.JavaDialectRuntimeData class in
drools-core. It contains a Map field called "store". All bytecode generated
is stored in there, but there is no built-in way of dumping it. So either
your tool allows you to inspect it in memory, or you change the class to
dump it somewhere. Take a look at the writeExternal() method to understand
how we dump it during kbase serialization.
