---------------------------------
> ClassCastException in Filters.convert
> -------------------------------------
>
> Key: OPENJPA-457
> URL: https://issues.apache.org/jira/browse/OPENJPA-457
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 0.9.7, 1.0.0, 1.0.1
> Environment: openjpa 0.9.7, Sun JDK 1.5.0_12, MySQL 5.0.45, Ubuntu
> Linux 7.1
> Reporter: Anil Gangolli
> Assignee: Pinaki Poddar
> Fix For: 1.3.0
>
>
> I am seeing this problem in 0.9.7 but examination of trunk code suggests that
> the same bug is still present in current trunk.
> The exception occurs when Filters.convert(o,type) is called with o of class
> String and type Long.class.
> This leads to a ClassCastException at line 292 where o is cast to Number.
> The same path seems to be reached for any type assignable from Number, except
> Integer.class which is handled in a separate case at line 275.
> Example stacktrace fragment:
> Caused by: java.lang.ClassCastException: java.lang.String
