Re: [Cobertura-devel] report shows class statement as red on simplestatic class

[<dun...@bt...>]

...so you have to instantiate the class, even though it was never
designed for that.
 
Try adding "private JPAHelper dummy=new JPAHelper();"

Alan,

You're seeing the default constructor (equivalent to public JPAHelper()
{}) that is automatically generated when no constructors exist in the
source.  Cobertura operates on the byte-code and when a default
constructor is generated this way it maps to the class declaration in
the source.
