Possible IllegalArgumentException with PrivateReaderMethodFinder

[Colin]

I found that if your entity class has a method which resembles a
getter, but takes one or more arguments, then this exception can
occur:

java.lang.IllegalArgumentException: wrong number of arguments

I got around it my creating my own PrivateReaderMethodFinder which
skips methods (returned from beanClass.getDeclaredMethods) that have
arguments.

Hi Colin,

Thanks for reporting this. This is now enhanced in the main trunk to
avoid this:
