It seems like this project is pretty dormant, but I thought I would pass this along in case anyone else is interested. I went through the code to clean up the deprecation messages that show up when building for a JDK11 target. I realize that BeanShell2 is targeted for JDK1.8, but I wanted to squelch a run time message that shows up about an illegal module access in the Reflect class, and all of the other deprecation messages were easy pickings.
