Hello,
Please review the changes to remove the java launcher's data model
options -d32/-d64, these options existed to support Solaris dual-mode
operation, however for uniformity, these options were accepted by other
platforms as well. These options are now obsolete, and deprecated in
jdk9,and are now being removed.

This seems okay in itself, though I'm curious why you made the
launcher/jli responsible for treating -d32/-d64 as invalid options
instead of just passing them through to the VM to let it reject them
as it does any other non-existent option eg:
I mulled over this for sometime, and felt that since the launcher
supported these options before, it should give a better/reasonable
error message than the VM does. I am undecided. What do you think ?
> java -foo -version
Unrecognized option: -foo
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
I also see some pre-existing messiness you might want to tidy up while
you're in the area :)
OMG Pre-existing conditions. ;)
src/java.base/macosx/native/libjli/java_md_macosx.c
378 JLI_Snprintf(jvmcfg, so_jvmcfg, "%s%slib%s%s%sjvm.cfg",
379 jrepath, FILESEP, FILESEP, "", "");
The last two %s should just be removed instead of passing empty strings.
422 } else {
423 /*
424 * macosx client library is built thin, i386 only.
425 * 64 bit client requests must load server library
426 */
427 const char *jvmtypeUsed = "server";
428 JLI_Snprintf(jvmpath, jvmpathsize, "%s/lib/%s/" JVM_DLL,
jrepath, jvmtypeUsed);
429 }
I don't think we have ever had 32-bit client on OSX! So this whole
clause seems strange. That aside you can just hardwire %s/lib/server
instead of using the jvmTypeUsed variable.
+1, I think we did support 32-bit for sometime, in the early days of MacOSX.

src/java.base/unix/native/libjli/java_md_solinux.c
323 JLI_Snprintf(jvmcfg, so_jvmcfg, "%s%slib%s%sjvm.cfg",
324 jrepath, FILESEP, FILESEP, FILESEP);
Another strange version of this code - only 4 %s this time, but
adjacent FILESEP. :) I'm assuming this is from when <arch> was removed.
Urk.
Ok I will revisit the above, good catches!, and prepare
another changeset.

Thanks,
David
Thanks
Kumar
PS: Thanks to David Holmes and Igor Ignatyev the -d32/-d64 flags have
been
purged from internal test suites.
