Bug ID: 69914
Summary: Java Record Getter Method Access in JSP EL Tomcat 10
to 11 Regression
Product: Tomcat 11
Version: 11.0.14
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: EL
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: -------
In Tomcat 10.1.x (tested in 10.1.43) within a JSP we could access getter
methods on a record using just the property (.propertyName) notation in JSP EL.
Example:
public record Person(String firstName, String lastName) {
public String getFullName() {
return firstName + " " + lastName;
}
}
Add a Person as a request attribute (model attribute in Spring MVC):
model.addAttribute("person", new Person("Robert", "Smith"));
Access "fullName" in the JSP:
${person.fullName}
This works in Tomcat 10.1, but in Tomcat 11 (11.0.15) throws the error:
Caused by: jakarta.servlet.ServletException: jakarta.servlet.jsp.JspException:

Using the full method name in JSP EL works in both versions of Tomcat:
${person.getFullName()}
