persistenceUnitProperties on EntityManagerFactory must be parameterized
-----------------------------------------------------------------------

                 Key: JBSEAM-1952
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-1952
             Project: JBoss Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.0.CR1
            Reporter: Dan Allen
            Priority: Minor


The XML configuration schema boast support for persistence-unit-properties on the EntityManagerFactory component. However, the configuration does not work because  persistenceUnitProperties is not parameterized and therefore the Seam map converter cannot figure out what to do. If key/value pairs are specified, Seam fails to start.

Here is an example:

<persistence:entity-manager-factory name="emf" persistence-unit-name="pu">
  <persistence:persistence-unit-properties>
    <key>hibernate.hbm2ddl.auto</key>
    <value>create-drop</value>
  </persistence:persistence-unit-properties>
</persistence:entity-manager-factory>

Here is the exception that is thrown:

Caused by: java.lang.IllegalArgumentException: collection type not parameterized
	at org.jboss.seam.util.Reflections.getCollectionElementType(Reflections.java:188)
	at org.jboss.seam.Component$MapInitialValue.<init>(Component.java:2457)
	at org.jboss.seam.Component.getInitialValue(Component.java:526)
	at org.jboss.seam.Component.getTopInitialValue(Component.java:510)
	at org.jboss.seam.Component.initInitializers(Component.java:488)
	at org.jboss.seam.Component.<init>(Component.java:260)
	at org.jboss.seam.Component.<init>(Component.java:214)
	at org.jboss.seam.init.Initialization.addComponent(Initialization.java:940)

Unfortunately, the best option we have, from the converters that Seam supports, is to make it a Map<String, String>. In the patch supplied I have used this signature.
