I'm having this exception when I call
jobInDatabase = pm.getObjectById(DAOJob.class, job.getKey());
Causes the following exception
java.lang.ClassCastException: java.lang.Long cannot be cast to java.lang.Double

I'm not sure which field is throwing this exception? I've 3 doubles in the obj - weight 0 deliveryLongitude 0 deliveryLatitude 0
and the rest of the numbers are longs. This is only happening with this one object at the moment.
These values are set by default if no value is passed in. Going forward, maybe if I set these default values to represent actual doubles, it would rectify this problem.
Here are some of the logs on the server leading up to the exception:

-Any suggestions?
The user Andrei Volgin comment above was correct.
The datastore viewer fields are only float and int types. I edited a double value and it was stored as a Long.
I tried to replicate the issue by updating a field and initially it did not replicate, because it was getting the original object from the JDO cache.
Once a new instance started up on GAE "This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application."
And JDO went to retireve my newly updated object, I got a java.lang.Long cannot be cast to java.lang.Double.
Bottom line, don't update double values using the datastore viewer
