jdk.jmplst is not working in jdk1.8

[xinstein]

I'm using a macOS sierra

I used:
jar tf $JAVA_HOME/src.zip | sed -e 's#^src/##' > jdk.jmplst

Note I used src.zip because I can't find an src.jar anywhere in my java_home
I set the java_home according to the output of $(/usr/libexec/java_home)

I noticed that the jdk.jmplst such generated contains only paths to files ending with .java (instead of .class), and maybe that why it doesn't work.

Is there a solution for me?

Thank you very much!

It's a very handy plugin if jdk import works~
