I used the online regular expression formatter for JAVA ( https://www.freeformatter.com/java-regex-tester.html ), and the only expression that works out of the three I wrote is this: *Java Regular Expression :* .*\b(00:|01:|02:)\b.* *Entry to test against : *01:45 y otras cosas 00:33 02:01 05:00 que mas This Result , is OK! [image: Captura de pantalla_2020-10-12_14-36-30.png] But this expression does not work in *geoserver SLD*, the result of applying the style to my layer is empty, it does not classify any point. I understand that there is a problem at the geoserver + SLD level. Where should I report this bug?
