Internal Changes

Yasser's PR has been merged which contains a fix to double evaluation security vulnerability - it should solve any future attack vectors, yet it can impact your application if you have been depending on double evaluation.

How to test

• Run all your app tests, you shouldn't see any WARN log like below:

Expression [so-and-so] isn't allowed by pattern [so-and-so]! See Accepted / Excluded patterns at
https://struts.apache.org/security/

• See if following components are still functioning correctly regarding java-scripts:
  forms with client side validations
  doubleselect
  combobox
• Check also StreamResults, AliasInterceptors and JasperReportResults if they are still working as expected.
