public class ExceptionQueuedEventContext extends Object implements SystemEventListenerHolder
This helper class provides context to
the ExceptionQueuedEvent
regarding the state of the system at the
point in time when the ExceptionQueuedEvent
occurs and links
the ExceptionQueuedEvent
to the ExceptionHandler
by virtue of implementing
SystemEventListener
.

public static final String IN_BEFORE_PHASE_KEY
The presence of an entry under this
key in the Map
returned from getAttributes()
indicates the event occurred during the “before
phase” part of the current lifecycle phase.
public static final String IN_AFTER_PHASE_KEY
The presence of an entry under this
key in the Map
returned from getAttributes()
indicates the event occurred during the “after
phase” part of the current lifecycle phase.
