org.osgi.framework.BundleException

All Implemented Interfaces:

Serializable

public class BundleException
extends Exception

A Framework exception used to indicate that a bundle lifecycle problem occurred.

A BundleException object is created by the Framework to denote an exception condition in the lifecycle of a bundle. BundleExceptions should not be created by bundle developers. A type code is used to identify the exception type for future extendability.

OSGi Alliance reserves the right to extend the set of types.

This exception conforms to the general purpose exception chaining mechanism.
