Knut Anders Hatlen updated DERBY-5840:
--------------------------------------
Attachment: derby-5840-17-aa-property-conglomerate.diff
Attaching derby-5840-17-aa-property-conglomerate.diff which makes these changes:
- In LockSpace, many methods operate on a HashMap<Lock,Object>. Since the
values in those maps are always of type Lock, change the type of the maps to
HashMap<Lock,Lock>.
- Remove the SuppressWarnings annotations in PropertyConglomerate and make the
declarations strongly typed to avoid the warnings. Apart from adding type
parameters to collections, the trick here was to recognize that the property
derby.defaultPropertyName was always a FormatableHashtable, so when reading the
property we could just as well do a checked conversion to FormatableHashtable
instead of an unchecked conversion to Hashtable<Object,Object> or
Dictionary<Object,Object>.
All tests ran cleanly with the patch.

> Using Java 5 language features forces us to compile code at level 5 or
> higher. At this level, the compiler raises warnings not seen at lower levels.
> This issue is a place to discuss and attach cleanup to eliminate these
> warnings.
