Salikh, Good catch! You just saved the MMTk port 20 hours of debugging. Thank you :)

As as I know, currently on 32 bit platform (ia32) the array base offset is 12 for types of size <= 4. Double[] and long[] arrays have array base offset 16. on 64 bit platforms, if the vtable pointers are compressed (they are now), the array base offset is the same as on 32 bit platforms. Should someone disable vtable reference compression, the array base offset will be always 16 (8 bytes vptr + 4 bytes flags + 4 bytes array size). --------------------------------------------------------------------- Terms of use : http://incubator.apache.org/harmony/mailing.html To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
