Bug ID: 69339
Summary: ClassFormatException in Java11 while compiling JSP
pages
Product: Tomcat 9
Version: 9.0.89
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: -----
There is prey weird behaviour that we are observing. When we import a class in
JSP that does not have any string + operations, it is working fine. But when
the imported class contains these operations, it is failing. For example:
Working class files:
public class App {
public string getName(){
String name = "test**";
return name;
}
}
public class App {
public string getName(){
String name = "test**";
return "test".concat(name);
}
}
Non-working class file:
public class App {
public string getName(){
String name = "test**";
return name + "fail";
}
}
Stacktrace:
