Not true. Modern JVMs with JIT compilation techniques are as fast - or
even faster - than C++ in general.

It depends what the developer wants to do with the CFX tag - they are
often reused and that reuse may well be on another platform.

C source code portability is achievable but it is *much* harder than
many people realize because so many platform differences exist. I
spent several years at a company that developed a C source code
analyzer (based on the ANSI-validated compiler I wrote) and we worked
with companies worldwide, solving their portability problems... and we
charged $9,000 per server for that checker... they were having so many
problems with C portability that they gladly paid for this tool over
and over again.

But JDBC *is* portable so there's no reason to use ODBC.

There are plenty of portable ways to do lots of things.

Pointers were the single most problematic aspect of C and C++ for many
developers and were the primary source of application unreliability
(memory leaks, reusing freed memory etc). Implementing a safe virtual
machine that supports unmanaged pointers is extremely hard - they're
just not worth the hassle to be honest.
