Unable to start GeoServer 2.27.x with last version of COG extension

Hello,

Apparently the last changes on the 2.27.x branch for the COG extension has introduced a regression preventing GeoServer to start. The error is:
Caused by: java.lang.NoSuchMethodError: 'void org.geoserver.config.util.XStreamPersister.registerBriefMapComplexType(java.lang.String, java.lang.Class)'

If I remove the extension my geoserver docker image works nicely (but I need it for this environment).

I think it is related to this commit: [Backport 2.27.x] [GEOS-11917] INSPIRE configuration does not get pro… · geoserver/geoserver@1223f7e · GitHub

I tried to run the 2.27.2 version. Is a 2.27.3 version planned to be released?

Release Schedule · geoserver/geoserver Wiki · GitHub says 2025-10-18

what about running a snapshot of geoserver as you seem to be running a snapshot version of the plugin, or build and package the plugin from the 2.27.2 tag

I run the snapshot version of the plugin because for a community extension it is the only available version to download. There is no snapshot version of 2.27 as docker image, only a 2.28 version.

I think I will have to build the extension with the right version.

There has bene indeed a method rename to fix a tipo (I was not happy to see It but the other reviewer insisted on it).
Community modules are exposed to this kind of issue when you mix a release version of Geoserver with a community module. Best course of action is to push funding towards getting the module up to extension status. The COG module has two issues left: handling large COG files efficiently, without having to set a system variable, and the online testing (that’s missing). Packaging is also a issue, cloud libraries have a large, unpredictable across versions, set of dependencies. We’d also need to run online tests against the module zip packages

Daniele Romagnoli today reverted the API change in the stable (2.27.x) and maintenance (2.26.x) series, starting tomorrow nightly builds of community modules should be back to compatible with the 2.27.2 release.

That said, if anyone here depends on a community module, I would strongly suggest to work towards getting the modules in supported land (and yes, that takes either your development hours, or funding).

Cheers
