Hi Devon,
The sequence you provided works doesn't crash for me for jqt on a mac.

However the display is not consistent, as sometimes the plot looks like a
Spirograph design (like a rotated rectangle in place without refresh) and
sometimes it looks like two straight lines (one vertical and one connected
around the midpoint of the vertical and extended at an angle downwards - ASCII
art below although the slope is not as steep as shown). Spirograph display has
x-axis _300 to 50, two line display is 0 to 1.4e14

So, something seems to be going on. I only noticed this after running the
sequence on an instance of jqt and jconsole at the same time and even then it
was not consistent.
Hope this helps,
Cheers, bob
