FYI...
This issue was resolved by changing the last line
from this:
List groups = (List) q.execute(group_keys);
to this:
List groups = (List)
q.execute(Arrays.asList(group_keys));
Thanks,

group_keys is an array containing several "Key" values. I want to
perform a query that returns all "Group" items that have a key value
that exists in the array "group_keys".

As far as I know, the execute() method does not work with arrays arguments.
Modify the declaration of your 'group_keys' from 'Key[]' to 'Key'.
By the way, all query errors happen to be assigned to the 'execute' line in
debug mode.

Cryille,
Using debug mode, I can see that the group_keys array is being
populated correctly.
The error is appearing on the last line:
List groups = (List) q.execute(group_keys);

Didier,
Thanks for the suggestion, but I have deleted the datastore and tried
again with a fresh datastore, and the same thing happens.
Thanks,
