Re: Catching JVM exceptions

[A. Sundararajan]

Just adding to what Attila said:

For ECMAScript Error objects there is a property called 
"nashornException" that returns the underlying Java exception thrown.

try {
     func();
} catch (e) {
     print(e.nashornException);
}

Java exceptions are thrown "as is" (no wrapping of Java exceptions as 
ECMAScript objects)

We don't wrap them initially, so "e" can be a java exception; catch(x if x 
instanceof java.io.FileNotFoundException) should work.

How do you catch JVM exceptions in Nashorn? This is how it works in Rhino:

            try {
                ...
            }
            catch (x if x.javaException instanceof 
java.io.FileNotFoundException) {
            }
