<AWT Dev> [9] Review request for 8166591 [macos 10.12] Trackpad scrolling of text on OS X 10.12 Sierra is very fast (Trackpad, Retina only)

[Sergey Malenkov]

I've got old MacBook Air 2011, 11" non-Retina display.  I installed
Sierra and reproduced the fast scrolling issue.  Now I have no idea
when it can be reproduced and when cannot.  Then I installed 10.12.1
beta (16B2333a).  Seems that the issue is not reproducible with a
system terminal anymore, but it is still reproducible with JDK.  My
first simple patch solves this issue.  Now I'm building new custom JDK
with the patch we created together. Stay tuned...
