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

[Keith Kriewall]

Hi 2d Devs,

The addition of BufferedImage.isStandard() has absolutely killed drawing performance for our application.  BufferedImage types that used to be set to optimized types (e.g. TYPE_INT_BGR) are now set to TYPE_CUSTOM, due solely to the classloader used to load the class.  It appears that unless we load our subclasses of ColorModel via the bootclassloader, we're stuck.  I've posted 9004714 to Oracle's bug database with a test app.

Can anyone on this list comment on this change in 7u25, provide a workaround, and/or provide a fix to bug 9004714 for future 7u releases?

Thanks,

-Keith
