<%@ page language="java" contentType="text/html;charset=UTF-8"

exception.printStackTrace();

Validation message:
Null pointer access: The variable exception can only be null at this
location

Why?!

Hi Eugene,

Looks like we were missing the initialization of the 'exception' field during JSP translation. This caused 'exception' to only ever be null, and thus producing the problem that you see. I've gone ahead and fixed this via https://bugs.eclipse.org/373410.

If it is hampering your development, there are validation severity settings that are accessible from the Preferences. Navigate to Web > JSP Files > Validation and then under the Java section, you can change "Null pointer access" to something less severe.

Thanks for catching this!

Thanks
But:
Target Milestone: 3.4 M6
Can you add bugfix in 3.3.2 ?

3.3.2 shipped nearly a month ago; there is no adding to it. 3.4 will be out in June.
