I'm using GT2.3.4 and here is the stack trace:
java.lang.RuntimeException: visit(Filter) unsupported
at
org.geotools.filter.visitor.DuplicatorFilterVisitor.visit(DuplicatorFilterVisitor.java:87)
at schmitzm.geotools.FilterUtil.cloneFilter(FilterUtil.java:28)
Meanwhile I recognized that I can avoid this error by setting the
"strict"-Flag in DuplicatorFilterVisitor constuctor to FALSE.
BUT: I'm not really sure, that I get a REAL clone of the filter, because
the phenomenon mentioned in an former mail still occurs...
