App Engine 1.7.5 does not create a new local_db.bin datastore file

I just upgraded to the GAE SDK 1.75 from 1.6.1. I deleted local_db.bin so that the new one is created by the application engine. My application is perfectly deployed to the local application server. However, when I send a request to an application that requires data from the data store, I get the following in the console:

INFO: backup storage, C: ... \ war \ WEB-INF \ appengine-generated \ local_db.bin, does not exist. It will be created.

The local_db.bin local file is never created, and I get the following exception:

org.apache.jasper.JasperException: java.lang.IllegalStateException: response already made

When I go back to 1.6.1, a local data store file is created and everything seems to work again.

Does anyone have an understanding of this problem? -Thanks.

Upgrade to GAE 1.8.1 or later and upgrade Java to 1.7.X. Once in the data warehouse, you have to start your project with the V2 data core, which gives you JDO 3.0
