copyElementAndCheckReference

@NotNull
public static @NotNull org.apache.jackrabbit.oak.query.ast.AstElement copyElementAndCheckReference(@NotNull
 @NotNull org.apache.jackrabbit.oak.query.ast.AstElement e)

as the AstElement.copyOf() can return this is the cloning is not implemented by the subclass, this method add some spice around it by checking for this case and tracking a DEBUG message in the logs.

Parameters:

e - the element to be cloned. Cannot be null.

Returns:

same as AstElement.copyOf()
