Well that's the theory but I think you'll find in practice that real
JITs cheat and inline object allocation using their knowledge of the
GC internals.
And there is no way that a JIT is going to implement synchronized

This subject has been covered in detail at least twice already.
There is no need for any function call on the fast path of the
allocation sequence. In a Java in Java VM the allocation sequence is
inlined into the user code. This has considerable advantages over a
few lines of assembler.
