Yes, --patch-module is needed to compile the tests "as if" they are part of the 
module, e.g.

   javac --module-path classes:junit.jar --patch-module m=src/test/java 
--add-reads m=junit -d test-classes \
       src/test/java/p1/P1Test.java

Thanks a lot, Alan!

The surprise for me was that --patch-module is used for source folders, too. I 
thought it was only for binaries.

But I noted I also have to add "--add-modules=junit" or the "--add-reads 
m=junit" will give an error that module junit cannot be found.
So the command has to be:
    javac -d target/test-classes --patch-module m=src/test/java --module-path 
target/classes:junit-4.8.2.jar --add-modules=junit --add-reads m=junit 
src/test/java/p1/P1Test.java

I’m not sure if that is a bug or a feature.  BTW, I noted that "javac -help" 
doesn’t mention --patch-module and --add-reads at all (only --add-modules)


Use "javac -X" or "javac --help-extra" to see help on additional 
options, such as less common or more advanced options.
