I currently try to build like described here: https://github.com/laeubi/lemminx-maven/blob/master/CONTRIBUTING.md

The log is all spammed with these repeated exceptions, the build succeeds but this does not look right

It is the same issue than eclipse-lemminx/lemminx#1589

It is the same issue than eclipse-lemminx/lemminx#1589

Indeed, an issue from upstream, nothing lemminx-maven can do here I guess.
