JSDT VariableDeclarationExpression in For-Statement drops "var" [message #1582119]

I suspect a bug in the way "for"-statements are handled:

The statement "for(var i = 0; i < 5; i++);" gets parsed to "for ( i=0; i < 5; i++) ;" - i.e. the variable declaration is dropped and only the VariableDeclarationExpression "i=0" remains. The two are semantically different.

Any ideas?

Example code:

ASTParser parser = ASTParser.newParser(org.eclipse.wst.jsdt.core.dom.AST.JLS3);
parser.setSource("for(var i = 0; i < 5; i++);".toCharArray());
JavaScriptUnit cu = (JavaScriptUnit) parser.createAST(null);
Statement statement = (Statement)cu.statements().get(0);
System.out.println(statement);

This prints "for ( i=0; i < 5; i++) ;" not "for(var i = 0; i < 5; i++);".
(Tried with the luna release.)
