Note: before you ask, yes I did parser.setResolveBindings(true); Smile

In the resulting AST, accesses to the length attribute of an array is a FieldAccess ASTNode (which is perfectly ok)

If I get the binding of this node (node.resolveFieldBinding()) I get an IVariableBinding. Now if I do a getDeclaringClass() on this binding, the result is null. Sad

That might be considered OK given that a Java array is not really a class (well I don't think it is ...?)

The problem is, how do I know that the 'null' does not come from a missing binding (some problem in the parsing), but from the fact that this is an array's attribute.
Or is it a bug in the binding resolver?

Could you please provide a complete test case and attached it to a bug report against JDT/Core ?
As soon as we get your test case, we can investigate what is going on.
