method private static Object cloneClass2(Object obj, RVMType type) throws OutOfMemoryError , in class org.jikesrvm.runtime.RuntimeEntrypoints, didn't consider float and double, is that a possible bug? I didn't test it, just a question.

Hi,

The float and double cases are actually covered by the following checks in
that method:

if (size == BYTES_IN_INT) { /* handles floats */

if (size == BYTES_IN_LONG) { /* handles doubles */

Note that float and int have the same number of bytes (4), and double and
long have the same number of bytes (8).

cheers,
Mike
