> is:
> throw new RuntimeDroolsException( "Unable to load dialect '" + dialectClass + ":" + dialectName + "'" );
> should be:
> throw new RuntimeDroolsException( "Unable to load dialect '" + dialectClass + ":" + dialectName + "'" , e);
> Symptom:
> When a required library is missing (such as mvel), an Exception "java.lang.RuntimeException: org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialect:java'" is thrown. With the fix, it will say "Caused by: java.lang.NoClassDefFoundError: org/mvel/integration/VariableResolverFactory..."
