Dominik Reinarz commented on IO-773:
------------------------------------
Passing a serializable lambda should work with 2.12.0?
if I use RegexFileFilter(pattern, (Function<Path, String> & Serializable) p ->
p.getFileName().toString()):
java.lang.ClassCastException: cannot assign instance of
java.lang.invoke.SerializedLambda to field
org.apache.commons.io.filefilter.RegexFileFilter.pathToString of type
java.util.function.Function in instance of
org.apache.commons.io.filefilter.RegexFileFilter
at java.base/java.io.ObjectStreamClass$FieldReflector.setObjFieldValues
