> This code used to work under jexl2
> {code:java}
> public enum Gender { MALE, FEMALE};
> public static void main( String[] args ) throws ClassNotFoundException {
>     JexlEngine jexl = new JexlEngine();
>     Record r = new Record();
>     r.setHeader(new RecordHeader());
>     JexlContext jc = new MapContext();
>     jc.set("r", r );
>     jc.set("com.sytrue.objects.Gender", Gender.class );
>     Expression e = jexl.createExpression( "r.header.gender=com.sytrue.objects.Gender.FEMALE"
);
>     System.out.println( e.evaluate(jc) );
> }
> {code}
> but under jexl3 it throws an exception:
> {code:java}
> public static void main( String[] args ) throws ClassNotFoundException {
>     JexlEngine jexl = new JexlBuilder().create();
>     Record r = new Record();
>     r.setHeader(new RecordHeader());
>     JexlContext jc = new MapContext();
>     jc.set("r", r );
>     jc.set("com.sytrue.objects.Gender", Gender.class );
>     JexlExpression e = jexl.createExpression( "r.header.gender=com.sytrue.objects.Gender.FEMALE"
);
>     System.out.println( e.evaluate(jc) );
> }
> {code}
> The exception is:
> {code}
> Exception in thread "main" org.apache.commons.jexl3.JexlException$Property: com.sytrue.objects.record.app.JexlTestApp.main@1:42
unsolvable property 'FEMALE'
> {code}
> Temporary workaround is using the valueOf method:
> {code:java}
> JexlExpression e = jexl.createExpression( "r.header.gender=com.sytrue.objects.Gender.valueOf('FEMALE')"
);
> {code}
> It seems that I no longer can access the enum type in jexl3.
> Is there any reason this doesn't work anymore or it is a bug
