Línea de trabajo

Start by inspecting the attached test.js and the JavaScript served as faces.js.jsf in the TomEE reproduction; compare it with the version served under Mojarra on WildFly. Run the provided Maven sample with Java 17 and TomEE 10.0M2 to reproduce the parser error. Done means identifying and addressing the incompatibility so the Jakarta Faces page with an Ajax call loads without the exception.

Descripción

Using HtmlUnitDriver 4.23.0, I observe an ugly EvaluatorException when calling a minimal Jakarta Faces page with just an Ajax call:

org.htmlunit.corejs.javascript.EvaluatorException: syntax error (http://localhost:8080/test/jakarta.faces.resource/faces.js.jsf;jsessionid=6C2C888968266540AA88DD3A0FCD95C5?ln=jakarta.faces&stage=Development#194)

Posting the full stacktrace probably does not bring any additional information.

I have a sample to reprocuce, but i requires a few steps:

  1. download TomEE 10.0M2 from https://tomee.apache.org/download.html (you need "TomEE Webprofile zip") and unzip
  2. you need Java 17
  3. rename attached "test.war.zip" to "test.war" and copy it to to TOMEE_HOME\webapps:
    test.war.zip
  4. start TomEE: TOMEE_HOME\bin\startup.bat (or startup.sh)
  5. you can test the app by browsing to http://localhost:8080/test/index.jsf
  6. now launch attached sample "htmlunittest.zip" (a small Eclipse maven project): mvn clean compile exec:java - you should see a large exception.
    htmlunittest.zip

From the log output, I picked this JavaScript file:
test.js.zip

I ran my sample also on WildFly, which includes the Mojarra Jakarta Faces implementation, and here the error did not happen. So maybe it is really a syntax error?
