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)
