> The AST generated by org.eclipse.wst.jsdt.core.dom.ASTParser.createAST() is incorrect.
> For the expression `var a = b`, the AST does not recognize `a` as the variable, instead representing the statement as `var b`
> E.g. (Parentheses indicate the ASTNode's toString())
> Statement: var b = 15; 
> AST:
> [...]
>     VariableDeclarationStatement   (var b=20)
>       InferredType 
>       VariableDeclarationFragment  (b=20)
>         SimpleName                 (b)
>         NumberLiteral              (20)
> Statement: var b = a;
> AST:
> [...]
>     VariableDeclarationStatement   (var a)
>       InferredType
>       VariableDeclarationFragment  (a)
>         SimpleName                 (a)
> The problem is not present for other node types (e.g. Assignment), not is it present when the right-hand-side contains an expression (e.g. `var c = b + a`)
