ContentException	Indicates that there was a network, parser, cache error when performing a query.
CrossThreadException	Exception thrown when a non Thread-safe modification is done in the wrong thread.

IllegalArgumentException	Thrown to indicate that a method has been passed an illegal or inappropriate argument.
IllegalMonitorStateException	Thrown to indicate that a thread has attempted to wait on an object's monitor or to notify other threads waiting on an object's monitor without owning the specified monitor.
IllegalStateException	Signals that a method has been invoked at an illegal or inappropriate time.
IncompleteAnnotationException	A mirror of java.lang.annotation.IncompleteAnnotationException.
IndexOutOfBoundsException	Thrown to indicate that an index of some sort (such as to an array, to a string, or to a vector) is out of range.

NoSuchElementException	Thrown by the `nextElement` method of an `Enumeration` to indicate that there are no more elements in the enumeration.
NullPointerException	Thrown when an application attempts to use `null` in a case where an object is required.
ResourceNotFoundException	This exception is thrown by `ResManager` when a requested resource can not be found.

Class Overview

RuntimeException is the superclass of those exceptions that can be thrown during the normal operation of the Java Virtual Machine.

A method is not required to declare in its throws clause any subclasses of RuntimeException that might be thrown during the execution of the method but not caught.

Inherited Methods

From class java.lang.Throwable

From class java.lang.Object

boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
final Class<?>	getClass() Returns the runtime class of an object.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait(long timeout, int nanos) Causes current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
final void	wait() Causes current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
