IDEA-40439 "[Ljava.lang.String;" not understood in constructor-arg

Issue is visible to: All Users

Product: IDEA

Build: 7126
Evaluator: false
Name: William Poitras
Comment: In IDEA 7.0M2: In a Spring context (or perhaps any DTD based XML file) "[Ljava.lang.String;" is not considered a valid type (in this case as a value for the "type" attribute of a constructor-arg element). The inspection claims: "Cannot resolve class String;" when in fact this is the correct class name for an array of strings. For example:

?xml version="1.0" encoding="UTF-8"?>

Surely there must be a cleaner way than to write synthetic JVM array class names in the "type" attribute..

What do you mean Taras?

I mean this: using type="[Ljava.lang.String;" is an ugly hack, and the reporter should thank IDEA for marking it red :)

If the class has multiple overloaded array-based constructors, a clean solution would be to create a static factory method with some specific name ("createFromStringArray"), and use that in the spring xml. Other refactorings are possible as well.

Anyway, valid types should not be highlighted
