The copyOf() method at src/main/java/org/apache/maven/shared/filtering/MavenResourcesExecution.java lines 428–450 omits these fields:
flatten (line 113) — controls flattened directory outputpropertiesEncoding (line 57) — encoding for .properties filesdelimiters (inherited from AbstractMavenFilteringRequest, line 75) — custom expression delimiter specificationsinterpolatorCustomizer (inherited from AbstractMavenFilteringRequest, line 84) — custom interpolator consumer
The default constructor calls initDefaults(), which sets delimiters to ["${*}", "@"]. If a caller had configured custom delimiters or the other missing fields, the copy silently loses them. Any code path that creates a defensive copy (e.g., mavenResourcesExecution == null ? new MavenResourcesExecution() : mavenResourcesExecution.copyOf() in BaseFilter line 65) will produce an incomplete copy.
