| This method:
org.geotools.process.raster.MultiplyCoveragesProcess#execute Sets the coverages to be multiplied like this:
param.parameter("Sources").setValue(sources); This works for JAI-EXT, but when using the older jai, it expects its parameters to be named 'source0' and 'source1'.
So adding these lines should fix it:
param.parameter("source0").setValue(coverageA);
param.parameter("source1").setValue(coverageB);
Currently a rather ugly NullPointerException is thrown when using JAI:
