The diamond problem.  I'm not really up on the details however.

I can tell you from hanging out on the lambda-dev list (Java 8 features) 
that Brian Goetz has pushed back strongly on any sort of multiple 
inheritance.  Apparently the diamond problem is a real bear and 
introduces real complexity into both the compiler and the user code that 
can cause big problems in the long run.
