Description

Reading from the following .properties file fails:

_=description:String,name:String
GenericEntity.f004=description-f004|name-f004
GenericEntity.f007=description-f007|

The second feature has an empty name, but the parser fails. Solution is to replace

text = line.substring(split + 1).split("\\|");

by 

text = line.substring(split + 1).split("\\|", -1);

at PropertyAttributeReader.

Jody, I've committed a patch and updated test case at r37006 as I need the geoserver build going. Please verify its correctness before closing the issue?

Cheers,
Gabriel

I am a bit confused; my copy of Java does not have javadocs for split( string, int ) so I cannot quite tell what you are doing.
There are a couple of places in the multiline patch where training spaces will not work; namely:

http://download.oracle.com/javase/6/docs/api/java/util/Properties.html#load(java.io.Reader)

Reading that more carefully I see only leading whitespace is ignored; so I will no longer call String.trim(). this does mean if you require leading whitespace we will need to "escape" it with backslashes.

I think we better escape the | character as well.

I cannot tell what you are expecting from an empty attribute: null or "" ? Your patch does not test the result.
We explicitly code up "<null>" to represent null; but reviewing the code returns "" as null if the attributeType isNillable and not empty string.

Your patch adds a new entry "fid5" which conflicts a bit with the use of fid5 as explored when making concurrent modifications.

Okay commit made to address leading whitespace only; explicit test cases for "table". Will leave you fid5 changes in as I am worried to fix them.

Please review commit when ready gabriel and close when happy.
