RFR [9] 8134254: JShell API/tool: REPL for Java into JDK9

[Jan Lahoda]

Hi,

I'd like to ask for a review of top-level and jdk repository changes 
needed for the JShell/REPL tool.

The top-level repository changes:
http://cr.openjdk.java.net/~rfield/jshell_base_webrev_v0/

The jdk repository changes:
http://cr.openjdk.java.net/~rfield/jshell_jdk_webrev_v0/

Any feedback is welcome.

Thanks!

Jan
