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

[A. Sundararajan]

Hi,

AFAIK "javax.script.filename" is not set nashorn code anywhere. It is 
just read to find source name for engine.eval calls.

"load" builtin is not related to jsr-223 API. It works regardless of 
jsr-223 usage and so it does not use (nor writes!) javax.script.filename 
property.

Is there a source link (the links in your email give me "error") or a 
standalone test?

Thanks,
-Sundar
