Andy Jefferson commented on JDO-678:
------------------------------------
Well a Properties ought to have String values only (even though it actually
implements Map<Object,Object>). A vendor may allow non-String values
(setProperty(String, Object)). For example, the PMF has a setting
javax.jdo.option.DatastoreReadTimeoutMillis which is an integer, and the PM
could allow setting of the same thing taking in an Integer. Vendor specifics
may also be non-String.

> It would be desirable to be able to set properties on the PersistenceManager,
> so as to be able to configure/change behaviour for a PM. Currently the PM is
> generated with particular configuration (from the PMF) and allows specific
> options to be set. But what about vendor extensions ? Having a general
> setProperty/getProperty/getSupportedProperties would be useful, and could
> also encompass the existing detachAllOnCommit, IgnoreCache, etc settings.
