Break is missing in switch (f.getPrimitiveType()) { case CHAR: } at QueryOptimizer.determineIndexToUseSub()

By the way, specifying char value right in the filter condition is not working as well:
q.setFilter("ch == 'a' || ch == 'z'");

Error is: Exception in thread "main" javax.jdo.JDOUserException: Query parsing error at 'a' near position 7: Incompatible types,
found 'String', expected: char. Query= ch == 'a' || ch == 'z'

Nice catch, that certainly qualifies for the bounty.

Btw, you can use the following construct to reset databases:

        if (ZooHelper.dbExists(dbName)) {
            ZooHelper.removeDb(dbName);
        }

I moved the second bug to a separate issue #104.
