About Question enthuware.ocpjp.i.v11.2.3028 :

[wakedeer]

I suppose you have a typo in the explanation
javac --module-source-path src --module-path thirdpartymodulesutils.jar -d out --module modules should be thirdpartymodules/utils.jar

[admin]

You are right. Fixed.
thank you for your feedback!

[powerofviva]

last answer should be either -m or --module
-module is incorrect.

[admin]

You are right. It should be --module. But it is a wrong option anyway.

thank you for your feedback
