Q: Scrambled PNG Images?

A couple versions of Java ship with broken native PNG support (gasp!). If you find your WMS image scrambled you can try the following:

ImageUtilities.allowNativeCodec("png", ImageReaderSpi.class, false);

This code fragments disables the native PNG reader (the pure Java one is fine; and in some platforms faster).
