Bug ID: 69696
Summary: Unexpected jsp page result if inner class changed to
compilation error
Product: Tomcat 11
Version: 11.0.6
Hardware: PC
Status: NEW
Severity: normal
Priority: P2
Component: Jasper
Assignee: dev@tomcat.apache.org
Reporter: ch...@msn.com
Target Milestone: -------
If a valid jsp file with inner class visited once and then the jsp inner class
source changed to invalid, its inner class (.class) retained in working
directory. Later, the request result is unpredictable.
1. source code of welcome.jsp
```java
<%
class Person {
int getAge() {
return 30;
}
}
%>
<html>
<body>
Welcome! Age:<%=new Person().getAge()%>
</body>
</html>
```
2. curl with expected result.
3. change the source code to:
```java
<%
class Person {
int getAge() {
return 30a; // obviously failed to compile.
}
}
%>
<html>
<body>
Welcome! Age:<%=new Person().getAge()%>
</body>
</html>
```
4. curl welcome.jsp, got 500 as expected!
5. curl welcome.jsp again quickly, got 200 response same with step 2.
