>                 Key: CHAIN-40

>             Project: Commons Chain
>          Issue Type: Improvement
>          Components: Base
>            Reporter: Cédric BODIN
>            Priority: Minor

> org.apache.commons.chain.impl.ContextBase should use java.util.LinkedHashMap (instead
of java.util.HashMap) : as its superclass,  and as the java.util.Map implementation for its
"descriptors" attribute.
> Indeed LinkedHashMap allow "insertion-order" iteration over the context, which is an
additional information about the chain execution (to know the order of the commands into the
chain).
> Moreover LinkedHashMap is a HashMap : so this enhancement is "transparent" for users
who didn't/don't/won't want to presume about context's iteration order.
> Thanks in advance.
