Using 7.2 beta or 7.2 RC1 , this method produces the error

The type of identify(null, resource, null) is erroneous

This problem does not occur in versions lower than 7.2 , ie 7.1

The same source tree is used in both cases as is the VM.

Java on osx 10.6.8

java version "1.6.0_33"
Java(TM) SE Runtime Environment (build 1.6.0_33-b03-424-10M3720)
Java HotSpot(TM) Client VM (build 20.8-b03-424, mixed mode)

Code 


 protected String getMimeType(String resource)
    {
        MagicMimeTypeIdentifierFactory factory = new MagicMimeTypeIdentifierFactory();
        MimeTypeIdentifier mimeTypeIdentifier = factory.get();
        return mimeTypeIdentifier.identify(null, resource, null); <--- ERROR
    }
