]
Mario Fusco resolved DROOLS-4750.
---------------------------------
Resolution: Explained
What the knowledge builder does at some point is invoking this
{code}
new EvaluatorRegistry(this.getClass().getClassLoader());
{code}
which has the side-effect of registering the custom operators like 'str' into the
parser. If you add that line as first statement of your first test you will see that it
will also succeed. Note however that the DRLParser is an internal class that is not part
of our public API and not intended for direct access by our end-users. For this reason I
don't think that we should change it in any way to make it work also without a
knowledge builder.
