Misleading compiler error on single line if statement [message #244243]

I'm running Eclipse 3.3 RC2 and had a compiler error for code which boiled
down to:

public class Test {
public void test() {
if (true)
String string = new String();
}
}

Obviously this is useless code (defining a variable in a single line if statement),
but the error annotations I received were misleading:

Multiple markers at this line
- Syntax error, insert ";" to complete Statement
- String cannot be resolved
- string cannot be resolved
- Syntax error, insert "AssignmentOperator Expression" to complete Assignment

I tried on javac and got

Test.java:3: not a statement
if (true) String string = new String();
^
Test.java:3: ';' expected
if (true) String string = new String();

This isn't much better, but at least it doesn't make me start thinking something
is wrong with my syntax or imports. Should I create a bug?

Yes. The problem comes from the grammar.
Technically speaking your code is a syntax error. We might try to see
how we can modify the grammar in order to digest such syntax and reject
the case later.
