This option was deprecated in JDK 23 so cannot be removed until 24, but the removal is really to make the option obsolete.  See the comments above your change in arguments.cpp.  The line should not be removed in arguments.cpp.  This change is wrong.

There is code that uses this option, that needs to be adjusted in the absence of this option.  I don't think this change compiles.  If you turn on GHA, in your settings you should see that this doesn't compile.

This RFE is assigned to me.  I would appreciate if you closed this PR and let me make this change.
