When I try to edit any metadata record in the metadata editor, I get
an HTTP 400 error while loading
and the metadata editor never loads (only the top bar is displayed).
This problem happens in 2 different servers (having the same exact
environment). However, it works correctly in my local Tomcat
installation. We have not modified Geonetwork code.
I have seen some relevant errors in the log, related with the wro4j
cache, but I have deleted the cache and the problem persists.
