get rid of "Could not find mediaLib accelerator wrapper classes"

[jai-interest-2]

Hi
How can I get rid of the exception "Could not find mediaLib accelerator wrapper classes.Continuing in pure Java mode."? I use Java (no native acceleration) jai-1_1_3-lib.zip on purpose. So I know that there are no wrapper classes and it should be that way. Is there any way to suppress the exception or should I catch it manually?

Not a bad idea: simple and direct.

Thanks,
