Resolve format problems in community modules

Travis CI is failing for format checks in two community modules, even if no changes have been made

[INFO] Processed 31 files (1 non-complying).
[ERROR] Found 1 non-complying files, failing build
[ERROR] To fix formatting errors, run "mvn fmt:format"
[ERROR] Non complying file: /home/travis/build/geoserver/geoserver/src/community/wps-remote/src/main/java/org/geoserver/wps/remote/plugin/output/XMPPRawDataOutput.java

and

[INFO] Processed 9 files (1 non-complying).
[ERROR] Found 1 non-complying files, failing build
[ERROR] To fix formatting errors, run "mvn fmt:format"
[ERROR] Non complying file: /home/travis/build/geoserver/geoserver/src/community/security/keycloak/src/main/java/org/geoserver/security/keycloak/GeoServerKeycloakFilter.java

So it must be bad in master.
