Ah yes, you can get these if you are debugging for some time and then
resume your app. I have also had this when I am working with a lot of
data - but usually more than the live servers could handle in 30
seconds anyway. The local datastore seems to reclaim objects too
quickly sometimes. But this is only a local issue - not a problem in
production.

Hi All,
I need a hint. I'm running JUnit tests on a local datastore. I have
multiple tests that pass when run by themselves and fail when run with
the other tests. The specific failure is a DataStoreFailureException
with detail message: "ApplicationError: 3: handle 14 not found".
The stacktrace is not that informative:
com.google.appengine.api.datastore.DatastoreFailureException: handle
14 not found

The tests do setUp and tearDown as suggested in the how-to on JUnit
tests:
@Override
public void setUp() throws Exception {
ApiProxy.setEnvironmentForCurrentThread(new TestEnvironment
());
ApiProxy.setDelegate(new ApiProxyLocalImpl(new File(".")){});
ApiProxyLocalImpl proxy = (ApiProxyLocalImpl)
ApiProxy.getDelegate();
proxy.setProperty(LocalDatastoreService.NO_STORAGE_PROPERTY,
Boolean.TRUE.toString());
LocalDatastoreService datastoreService =
(LocalDatastoreService) proxy.getService
(LocalDatastoreService.PACKAGE);
datastoreService.clearProfiles();
super.setUp();
}
@Override
public void tearDown() throws Exception {
super.tearDown();
ApiProxyLocalImpl proxy = (ApiProxyLocalImpl)
ApiProxy.getDelegate();
LocalDatastoreService datastoreService =
(LocalDatastoreService) proxy.getService
(LocalDatastoreService.PACKAGE);
datastoreService.clearProfiles();
ApiProxy.setDelegate(null);
ApiProxy.setEnvironmentForCurrentThread(null);
}
It appears that something is breaking the local data store in a way
that is not cleared between tests. Prior to the failure, the failing
test successfully does an entity put which it is then trying to get
back. Any suggestions on a way forward?
Thanks,
Jim
