Description Roberto Javier Godoy

2007-08-26 13:27:36 EDT

Build ID: I20070625-1500

Steps To Reproduce:
1. Set Java Compiler | Errors/Warnings | Null pointer access = ERROR (either workspace or project-specific settings)

2. Write the following class

public class Test {
 public static void main(String[] args) throws Throwable{
 	Throwable t = null;
	throw t;
 }
}


ACTUAL BEHAVIOUR: The source code pass compilation without errors. 
If run, it throws a NullPointerException.

EXPECTED BEHAVIOUR: The compiler should have signaled an error "Null pointer access: The variable t can only be null at this location" at the line where t is thrown.

Suggested fix + test cases

ThrowStatement imitates what MessageSend does. Currently under test.
