Sebb created COLLECTIONS-458:
--------------------------------
Summary: AbstractUntypedCollectionDecorator<E, D> - is collection
allowed to be null?
Key: COLLECTIONS-458
URL: https://issues.apache.org/jira/browse/COLLECTIONS-458
Project: Commons Collections
Issue Type: Bug
Reporter: Sebb
The public ctor for AbstractUntypedCollectionDecorator<E, D> takes no argument
and so collection = null; however the protected ctor checks for collection
parameter != null.
The decorated() method says that all access to collection goes through it, and
there is no setter.
At present the only way to recover from calling the public ctor is for the
sub-class to set collection directly.
This is inconsistent.
The class is abstract and there appear to be no concrete subclasses. Looks like
the class might be superfluous, but if it is required, it should ideally have a
private final collection field.
