UndeclaredThrowableException
Stay organized with collections
Save and categorize content based on your preferences.
Thrown by a method invocation on a proxy instance if its invocation
handler's invoke
method throws a
checked exception (a Throwable
that is not assignable
to RuntimeException
or Error
) that
is not assignable to any of the exception types declared in the
throws
clause of the method that was invoked on the
proxy instance and dispatched to the invocation handler.
An UndeclaredThrowableException
instance contains
the undeclared checked exception that was thrown by the invocation
handler, and it can be retrieved with the
getUndeclaredThrowable()
method.
UndeclaredThrowableException
extends
RuntimeException
, so it is an unchecked exception
that wraps a checked exception.
As of release 1.4, this exception has been retrofitted to
conform to the general purpose exception-chaining mechanism. The
"undeclared checked exception that was thrown by the invocation
handler" that may be provided at construction time and accessed via
the getUndeclaredThrowable()
method is now known as the
cause, and may be accessed via the Throwable.getCause()
method, as well as the aforementioned "legacy
method."
