      1. Deploy the attached two-file "application". Observe that accessing `.../jastow-bug/test.jsp` results in an internal server error.

      2. Edit `test.jsp` and remove the apostrophe from "${0} ' ${fn:length ([1, 2])}".

      3. Now accessing the page gives `0 2`, as expected.

      Certain EL pieces result in unexplained org.apache.jasper.JasperException "contains invalid expression(s)" (the exception does not explain what is invalid). After lots of tries, I have narrowed it down: 1) there must be several EL pieces in one string; 2) there must be an apostrophe in between.

      This looks very similar to bug WFLY-4455. It breaks several pages in our application, blocking upgrade to WildFly 10.

      Example is attached.
