>             Project: Commons JEXL
>          Issue Type: Bug
>    Affects Versions: 3.2.1
>            Reporter: Henri Biestro
>            Assignee: Henri Biestro
>            Priority: Major
>             Fix For: 3.3

> WHAT:
> When running on Java9+, module encapsulation shields classes from usage even through reflection. The introspector is unfortunately not aware of this and which leads to unexpected runtime errors.
> Error looks like this:
> <code>
> class org.apache.commons.jexl3.internal.introspection.MethodExecutor cannot access class sun.net.www.protocol.https.HttpsURLConnectionImpl (in module java.base) because module java.base does not export sun.net.www.protocol.https to unnamed module @1e5c7dc
> </code>
> HOW:
> Through reflection (since we are still on Java8), add a check before introspection in the ClassMap.
