Jakarta Server Pages 3.1

Release for Jakarta EE 10

Jakarta Server Pages defines a template engine for web applications that supports mixing of textual content
(including HTML and XML) with custom tags, expression language, and embedded Java code, that gets compiled
into a Jakarta Servlet.

New features, enhancements or additions

• 40 Add an option to raise a PropertyNotFoundException
  when an EL expression contains an unknown identifier
• 42 Clarify the meaning of ‘scope’ in the context of
  scripting variables associated with custom actions
• 44 Clarify that the EL environment within a JSP has a
  set of default imports consistent with the default imports for the scripting environment. Refactor
  the ScopedAttributeELResolver to remove the special handling for imports and unresolved
  variables

Removals, deprecations or backwards incompatible changes

• Deprecate methods that override ELResolver.getFeatureDescriptors() as that method has been
  deprecated as of EL 5.0
• Deprecate the isThreadSafe page directive attribute as the related Servlet API interface
  SingleThreadModel has been removed as of the Servlet 6.0 specification
• 226 Deprecate the jsp:plugin action and related
  actions as the associated HTML elements are no longer supported by any major borowser
