If you change filter, profiling, trigger or probe settings for an active session, the new settings
can be applied immediately if you profile a 1.6+ JRE.
Apart from telemetry data, all recorded data including the heap dump in the heap walker will be
discarded in that case. When profiling settings are updated, a
bookmark will be added to views with a time-line, such
as the telemetry views. The application of the new profiling settings may take some time,
especially if filter settings are changed and the method call recording type is set to
dynamic instrumentation. In this case, changes in the instrumentation requires that
classes have to be retransformed to reflect the new filter settings.
If you profile a pre-1.6 JRE, you have to restart the session.
View settings on the other hand, are always adjustable during a running session and are saved
separately for each session.
