Data from an exception ends up in a web page.
Directly exposing error messages to the end user might expose relevant data about the application's configuration, and this could be exploited by an attacker.
Some operations should not be performed in production code, since they have no effect or have unpredictable effects, or since they might compromise the availability or security of your system.

public class WebProcessor : Page {
public void handleRequest(HttpServletRequest request, HttpServletResponse response) {
try {
process(request);
} catch (Exception e) {
response.getWriter().write("An error occurred: " + e.getMessage()); // "Exception Information Disclosure (Java)" warning issued here
}
}
}
The exception should be logged instead, and the error message displayed to the user should be generic, without real information about what happened coming from the exception.
Verify if the operation is adequate for production code. Remove it or transform it if that is not the case.
