Description
In method StubGenerator::generate_copy_longs(...) there are statements of the form

 __ align(6)

The intention presumably being to align the code buffer on a 64 byte boundary, however the implementation of align(...) does

void MacroAssembler::align(int modulus) {
  while (offset() % modulus != 0) nop();
}
