All Implemented Interfaces:

Serializable

public abstract class NashornException
extends RuntimeException

This is base exception for all Nashorn exceptions. These originate from user's ECMAScript code. Example: script parse errors, exceptions thrown from scripts. Note that ScriptEngine methods like "eval", "invokeMethod", "invokeFunction" will wrap this as ScriptException and throw it. But, there are cases where user may need to access this exception (or implementation defined subtype of this). For example, if java interface is implemented by a script object or Java access to script object properties via java.util.Map interface. In these cases, user code will get an instance of this or implementation defined subclass.
