I wasn't considering the performance impact on java jpeg. A fair
statement.

I'll look into that.

Also fair. I will send an email to 2d-dev with the same title. Figured I'd 

start here because it breaks all builds that don't use 
disable-warnings-as-errors.

Thank you everyone for your time. Feel free to follow these adventures
on 2d-dev. :)
