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

i updated gae sdk 1.75 1.6.1. deleted local_db.bin new 1 created app engine. app gets deployed fine local dev app server. however, when send request app requires getting info datastore next in console:

info: backing store, c:...\war\web-inf\appengine-generated\local_db.bin, not exist. created.

the local_db.bin datastore never gets created , next exception:

org.apache.jasper.jasperexception: java.lang.illegalstateexception: response has been committed

when revert 1.6.1 local datastore file created , seems work again.

does have insight on issue? -thanks.

upgrade gae 1.8.1 or above , upgrade java 1.7.x. coming datastore, have run project info nucleus v2 gives jdo 3.0
