#1316 Multi Rule Properties with delimiter not possible

[Andreas Dangel]

We have to provide multiple values to a rule property

     <rule name="myRule" message="Do not place to this package. Move to 
{0} package/s instead." 
class="com.xenovation.codestyle.pmd.rest.RestResourceSpecificPackage">
         <description>Please move your class to the right folder(rest 
folder)</description>
         <priority>2</priority>
         <properties>
             <property name="packageRegEx" value="com.aptsssss|com.abc" 
type="String[]" delimiter="|" description="valid packages"/>
         </properties>

The issue is, what the Property descriptor is not showing the attribute
delimiter nor is the default delimiter recognized properly.
We are getting a NullPointer in
BasicPropertyDescriptorFactory#delimiterIn()

It seems that neither the default delimiter nor a configured delimiter is working.

Workaround: fall back to a String property and split it manually in your rule.

Will be fixed with the next version.
