In JDK Mission control 8.0.0, The graphical representations of thread lanes
(or Thread Graph) is improvised.
The improvised Thread Graph is not fully accessible due to following issues
1. Thread graph comes up with set of buttons for zooming in/out the graph
plot area, resizing the thread lanes in graph etc. the purpose of these
buttons, is not read properly by assistive technology (JAWS)
2. The contrast of the contents in new Thread Graph is too low and not fully
3. The Thread Graph also pose difficulty when selecting and focussing thread
lanes within the graph (like any other graphs in JMC)
4. The Thread Graph poses difficulty in navigating to the Thread Lane Edit
window, for editing required events on a Thread Lanes in the graph.
JMC gives different tabular and graphical representations for events parsed
from a JFR dump, All required information about the parsed events such as
event name , event time, the thread from which the event originated etc are
available in Event Browser page in the form of a table.
The 'Improvised Thread Graph' is default thread visualization interface in
JMC, however a threads table and a toggle option to go the leagcy thread page
is available in JMC 8.0.0 Version.
This will be master bug for tracking all the accessibility related issues in new thread graph screen.
