[Jython-bugs] [issue2582] No >>> prompt with JDK 9, seems to be caused by illegal access

[Alan B. <re...@bu...>]

New submission from Alan Bateman:

`java -jar jython-standalone-2.7.0.jar` does not does not prompt for input. Running with `--permit-illegal-access` (new option in JDK 9 to reveal code doing bad things) may help understand what is going on, it seems that Jython has code that is trying to access a few JDK internal classes and fields.

$ java --permit-illegal-access -jar jython-standalone-2.7.0.jar
