ExtendedProperties uses "," to separate multiple values. So, you ask for a String, and
it has
a Vector. The same error happens when an entry is duplicated in two separate lines in
the file.
It has happened to me.
Alternatives can be found:
- throwing IllegalArgumentException with message "Asked for String, but XXX is a
Vector"
(suggesting something wrong with property/argument, instead of internal failure)
- Returning all the vector elements, comma separated (it solves the problem
with strings containing unescaped "," (this is the suggested solution here)
The general solution is to have a comment in TR.p pointing to the fact
that commas MUST be escaped when not element separators.
