You can evaluate:
function getScriptTrace() {
try {
throw new Error();
} catch (e) {
return e.stack
}
}
in your script and call the same from java code using
javax.script.Invocable.invokeFunction. ("stack" property and other
related extensions are documented here:
https://wiki.openjdk.java.net/display/Nashorn/Nashorn+extensions).
Or if you're okay with nashorn specific extension, you can use this API
from java code.
public static StackTraceElement[]
jdk.nashorn.api.scripting.NashornException.getScriptFrames(Throwable th)

Is there a way in Nashorn or javax.script to get a clean JavaScript-only
stack trace (not a Java stack trace, but only containing JavaScript code)
out of an exception thrown by a script? I don't see anything in the Nashorn
Wiki or javax.script -- apologies if I'm missing something there.
For instance, I can get a full Java stack trace when my script fails, but
I'd like to ignore all the Java stuff and give users the stack trace that
they would get if they were running the "plain" JavaScript natively rather
than inside Java.
