I crashed JVM manually and in the hs_err file I see that z17 is detected properly;

CPU: total 64 (initial active 64) system-z, g11-z17, ldisp_fast, extimm, pcrel_load/store, cmpb, cond_load/store, interlocked_update, txm, vectorinstr, instrext2, venh1, instrext3, venh2,bear_enh, sort_enh, nnpa_assist, storage_key_removal, vpack_decimal_enh, concurrent_function, out-of-support_as_of_tbd, aes128, aes192, aes256, sha1, sha256, sha512, ghash
