Hi Marek,
Yes, this is part of the new and improved data type mapping in PL/Java. 
Arrays are recognized as such so a varchar[] will map to a String[]. 
You'll find a complete list of mappings here: 
http://wiki.tada.se/display/pljava/Default+Type+Mapping.

Your current code rely on the fact that unrecognized types are all 
mapped to String.

Regards,
Thomas Hallgren
