Nashorn, javax.script.filename, and load()

[David P. Caldwell]

Yes, this test "works" (as in demonstrates the problem):

$ jrunscript -e
"load('https://bitbucket.org/api/1.0/repositories/davidpcaldwell/slime/raw/launcher/rhino/jrunscript/api.js?test=filename')"
stack = https://bitbucket.org/api/1.0/repositories/davidpcaldwell/slime/raw/launcher/rhino/jrunscript/api.js?test=filename
javax.script.filename = <string>
