>             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

> 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
>         at org.apache.openjpa.kernel.Filters.convert(Filters.java:292)
>         at org.apache.openjpa.jdbc.kernel.exps.UnaryOp.load(UnaryOp.java:110)
