-jar option and the modulepath

[Scott Palmer]

I’m curious how this relates to the -m or —module option.
I had though it looked like the module equivalent of the -jar option.

Cheers,

Scott

I do not see any support for a modulepath attribute in the Java 9 jar file documentation at https://docs.oracle.com/javase/9/docs/specs/jar/jar.html. My sense is that the -jar option commits the JVM to using a classpath.

Some prototypes during JDK 9 but the decision at the time was to defer it to some future effort. So when you run with `java -jar` then it puts the JAR file on the class path (exactly as it did in all previous releases).
