             Summary: [GSS](7.2.0) Apostrophe in an attribute with multiple EL parts breaks function lookup
                 Key: WFLY-9600
                 URL: https://issues.jboss.org/browse/WFLY-9600
             Project: WildFly
          Issue Type: Bug
          Components: EE, Web (Undertow)
    Affects Versions: 10.0.0.Final
            Reporter: Brad Maxwell
            Assignee: Tomaz Cerar
            Priority: Critical
         Attachments: jastow-bug.war.zip, jastow.diff

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.
