I'll admit that I don't really know Perl (I can muddle my way through 
reading it, but I have no hope of writing it anytime soon), so I'm 
probably more liable to grasp at stereotypes than honest truths.

My first thought of Perl is that it is often used for "little" scripts 
(e.g., a script that looks through a log file to find more useful data). 
I do know that it has some vague object-oriented features, but I believe 
that this feature lacks things like virtual methods and inheritance that 
are normally associated with object-oriented paradigms.

I suspect that you will most notably find grousing about explicit static 
typing, as opposed to Perl's implicit duck typing. To a lesser degree, 
people may grouse about Java needing to put methods in classes. It is 
possible (I'm really bordering on stereotype here) that your Perl 
programmers may grouse about how much more difficult it is to do textual 
manipulation in Java compared to Perl, particularly in the difficulty of 
handling stdin and running regexes.
