  // so keeping the size of this structure small has a big impact on footprint.
  //
- // We put all oops and method_size first for better gc cache locality.
- //
  // The actual bytecodes are inlined after the end of the Method struct.
  //
  // There are bits in the access_flags telling whether inlined tables are present.
  // Note that accessing the line number and local variable tables is not performance critical at all.
  // Accessing the checked exceptions table is used by reflection, so we put that last to make access
