Dear List!
We have old (2.12.3) geoserver that we have extended with some custom filter function by implementing FunctionFactory.
The filter functions are compiled to a .jar file that is copied to the WEB-INF/lib. Recently after a restart we had some GWC index issues that we fixed and now we have a strange error. WMS getcapabilities never returns the XML if our jar file is loaded. If I delete the jar file or recompile with empty getFunctionNames() XML is generated.
What I noticed before the first wms/getcapablilites call takes much longer (5-10 minutes) since it is building the XML from scratch in memory (later calls use this cache I guess). Turning on developer logging "I see [org.geoserver.wms.capabilities] - Adding GetLegendGraphic call as LegendURL” lines for all styles, however I do not see the style compiled. Is ther any way to which such debug on? I am pretty sure that there is some other problem with one of our styles and deleting the jar file cause null pointer exception when generating the XML and thus the style processing can go on (I see much more styles processed aka … GetLegendGraphic … calls when the jar is deleted).
Any idea on debugging this would be appriciated!
Thank you,
Laszlo
