> When 2 DRL rule files with different package names (the name following the 'package' keyword) each have a rule with the same name (the name being the quoted string that follows the 'rule' keyword), then the following exception occurs:
> org.drools.rule.InvalidRulePackage: Rule Compilation error The type Rule_Incident__Vehicle_0 is already defined
> 	at org.drools.rule.Package.checkValidity(Unknown Source)
> 	at org.drools.common.AbstractRuleBase.addPackage(Unknown Source)
> 	at driver.RulesTest.readRule(RulesTest.java:256)
> This occurs when using a single org.drools.rule.Package object, as in:
>     private void test(Reader source1, Reader source2) throws Exception {
>         PackageBuilder builder = new PackageBuilder();
>         builder.addPackageFromDrl( source1 );
>         builder.addPackageFromDrl( source2 );
>         Package pkg = builder.getPackage();
>         RuleBase ruleBase = RuleBaseFactory.newRuleBase();
>         ruleBase.addPackage( pkg );
>     }
> If, on the other hand two org.drools.rule.Package objects are used, as in:
>     private void test2(Reader source1, Reader source2) throws Exception {
>         PackageBuilder builder1 = new PackageBuilder();
>         PackageBuilder builder2 = new PackageBuilder();
>         builder1.addPackageFromDrl( source1 );
>         builder2.addPackageFromDrl( source2 );
>         Package pkg1 = builder1.getPackage();
>         Package pkg2 = builder2.getPackage();
>         RuleBase ruleBase = RuleBaseFactory.newRuleBase();
>         ruleBase.addPackage( pkg1 );
>         ruleBase.addPackage( pkg2 );
>     }
> then one of the identically named rules is simply ignored.
> In either case, rule names must be globally unique.
