Prior to this commit, the ObjectIdentity id had to be a number. This
commit allows for domain objects to use UUIDs as their identifier. The
fully qualified class name of the identifier type can be specified
in the acl_object_identity table and a ConversionService can be provided
to BasicLookupStrategy to convert from String to the actual identifier
type.
There are the following other changes:
- BasicLookupStrategy has a new property, aclClassIdSupported, which
is used to retrieve the new column from the database. This preserves
backwards-compatibility, as it is false by default.
- JdbcMutableAclService has the same property, aclClassIdSupported,
which is needed to modify the insert statement to write to the
new column. Defaults to false for backwards-compatibility.
- Tests have been updated to verify both the existing functionality
for backwards-compatibility and the new functionality.
Fixes gh-1224
