I guess that I was not plain. The standard shell, sh, should not have
even attempted to execute a file that does not have the execute bit on.
But it does try to execute it despite the lack of the execute bit being
on. That is what is WRONG. I agree that the file should not have the
execute bit on. And the javac compiler generates it correctly, without
the execute bit.

Agreed.

Right. That is why the shell, sh, should not have even attempted to
execute the file when you only entered its name on the command prompt.
There is a "bug" in the standard shell, sh, if it tries to execute a
file which does not have the eXecute bit on.

The whole problem stemmed, IMO, from the shell trying to execute a file
which was not marked as executable. This is WRONG. And does not happen
with BASH or tcsh.
