My problems with java:
no unsigned ints
primitive are passed by value; arrays and user defined types are
passed by reference only (killing memory usage)
no operator overloading(looks at java.util.ArrayList)
no templates
no property syntax(getters and setters are used instead even if
you know the field is never going to be dynamic)
only and exactly one class per file(ALL THE IMPORTS)
every thing must be inside a class(globals and free functions
are static fields in a class)
This is all i can remember.
You forgot type removal for generics during compilation.
I dunno, while type erasure is certainly annoying when you actually need
information about the type, it's also eliminates template bloat. I think
the ideal system should be somewhere in between, where type erasure is
actively performed by the compiler where the type information is not
needed, while template instantiations are retained when it is needed.
This should keep template bloat under control while still offering full
template capabilities. D currently leans on the template bloat end of
the spectrum; I think there is much room for improvement.

Its a bit more then annoying. What happened when it was originally
implemented was basically hacking of the compiler to support it,
type erasure wasn't a design decision to my understanding.
Then again the last time I checked Java's reference compiler / jvm
source code it was a real mess to say the least.
If I remember right an xml parser lib was at the same level in the repo
as the compiler and nothing else at that level. This was only a few
years ago now.
I really hope I'm wrong or its changed since then but who knows.
