Windows Eclipse: jvm flag -Ddatastore.default_high_rep_job_policy_unapplied_job_pct does not work

[GoogleCodeExporter]

My development environment is Windows 7 x64 with Eclipse Kepler x64

What steps will reproduce the problem?
1. Open the guestbook archetype
2. Run unit tests and note the console indicates Master/Slave datastore:

com.google.appengine.api.datastore.dev.LocalDatastoreService init
INFO: Local Datastore initialized: 
    Type: Master/Slave
    Storage: In-memory

3. Modify pom.xml

<plugin>
  <groupId>com.google.appengine</groupId>
  <artifactId>appengine-maven-plugin</artifactId>
  <version>${appengine.target.version}</version>
  <configuration>
    <jvmFlags>
      <jvmFlag>-Ddatastore.default_high_rep_job_policy_unapplied_job_pct=20</jvmFlag>
    </jvmFlags>
  </configuration>
</plugin>

4. Run unit tests again and note the console still indicates Master/Slave:

com.google.appengine.api.datastore.dev.LocalDatastoreService init
INFO: Local Datastore initialized: 
    Type: Master/Slave
    Storage: In-memory

5. Sanity check by adding datastore configs to the LocalServiceTestHelper(s)

new 
LocalDatastoreServiceTestConfig().setDefaultHighRepJobPolicyUnappliedJobPercenta
ge(20)

6. Run tests again and see that they pass with the console indicating High 
Replication

com.google.appengine.api.datastore.dev.LocalDatastoreService init
INFO: Local Datastore initialized: 
    Type: High Replication
    Storage: In-memory

I use cross-group transactions, so I need the local datastore to run in High 
Replication mode. The LocalDatastoreServiceTestConfig is a workaround for my 
tests but I still can not run in Debug mode to test my client.

Thanks for your help.

Extra note: jvm flags -Xdebug and 
-Xrunjdwp:transport=dt_socket,address=1044,server=y,suspend=y work as expected
