Hi Jody and all, I did a little bit more of investigation, and I replaced arrayOverlap with a more generic FilterFunction_multipleEqualTo (better names are welcome) that is like FilterFunction_equalTo with an additional parameter to specify the MatchAction (ANY, ONE or ALL). Still open the reasoning on how to express array literals in ECQL. For my own use case I can move the arrayFromString function in my project code, but I think a more general solution to this problem could be useful to have in GeoTools.
