Rhino exports to scripts the Java exception as "javaException" property 
of the exception object, so you example can be written as:

         } catch (e) {
                   printStr("RESULT=FAILURE");
                   printStr(e.toString());
                   printStr(e.javaException.getMessage());
		  e.javaException.printStackTrace();
         }

In this way scripts can access "name", "message", "fileName" and 
"lineNumber" properties of the object e in the same way as they would 
access them for the standard EcmaScript exceptions.
