Sybex Practice Tests 11, Chapter 7, Q 21 (page 511)

[M Janssen]

Answer to Chapter 7, Q 21 says (page 511):
The -m option is not available on the javac command.

But javac --help displays:
...

 --module <module-name>, -m <module-name>
        Compile only the specified module, check timestamps

...

Answer B might still be the right answer as -m might not be commonly used, but in that case the explanation is wrong.
It seems Chapter 7 Q #63 has same error.
I hope this could be confirmed and included in the list of known errors.

[Jeanne Boyarsky]

Agreed. I've added this to the errata and credited you. Have a cow!

[M Janssen]

Thank you!
Could you also include Chapter 7 Q #63 in the list, since that question seems to have the same error?

[Jeanne Boyarsky]

Oh. I missed there were two instances. I agree it is the same problem. Added. Thank you for following up!
