How to build an element key

                 Key: JCS-47
                 URL: https://issues.apache.org/jira/browse/JCS-47
             Project: JCS
          Issue Type: Question
          Components: Documentation
    Affects Versions: jcs-1.3
            Reporter: Ronny Roeller
            Assignee: Aaron Smuts

I use a string as key for my elements. Now I was surprised to get this error message:

11:07:52,257 INFO  [CacheEventQueue] Cache event queue created: CacheEventQueue [listenerId=1501085802,
11:07:53,000 INFO  [STDOUT] org.apache.jcs.access.exception.CacheException: key must not end
with : for a put operation

I guess this means that colon is a special character, and can't be freely used as a key.

Unfortunately, I couldn't find any documentation on the project website what the constrains
are for keys. It would also be interested to know if there is anything else to be considered
when choosing the key, e.g. is there an advantage in using shorter keys?
