[Benchmarking] Java scalability issue slide

[Liujian (LJ) Qian]

  I talked to a Java2D folk yesterday, and there is no plan to fix it 
(yet).  He suggested using the openJDK's AA rasterizer as a drop-in 
replacement for the Ductus one in the production JDK.  And I plan to 
test that out, but before I do so just want to ask if you guys already 
tried this approach?  I believe you mentioned openJDK is too slow, but 
wasn't sure if you were using the whole openJDK stack, or just its AA 
rasterizer.

thanks
LJ
