[OpenJDK 2D-Dev] 7u25 kills 'blit' performance for any custom ColorModel class

[Keith Kriewall]

Hi Phil,

Can you set my expectations for if/when this problem will be fixed?  We can't upgrade past 7u21 until this gets corrected, or we find some kind of workaround.  Right now I can't envision a workaround for a Web Start environment.

Thanks,

-Keith

This is an unfortunate consequence of a fix a potential security issue.
The actual bug ID for this is 8019590. We'll take a look to see what can be done.
