+        Inclusion of this profile brings in Jasper, which is not distributed by default due to ASF licensing policy
+        regarding LGPL dependencies. A basic report is used instead.
+
+        Note: in the future, it may be better to use the jasperreports plugin at all times (so the compiled report is
+        included), so that we just require that the JAR be on the classpath to activate it. We haven't taken this step
+        here because the jasperreports plugin is not yet released.
