ClassCastException in Filters.convert
-------------------------------------
Key: OPENJPA-457
URL: https://issues.apache.org/jira/browse/OPENJPA-457
Project: OpenJPA
Issue Type: Bug
Affects Versions: 1.0.1, 1.0.0, 0.9.7
Environment: openjpa 0.9.7, Sun JDK 1.5.0_12, MySQL 5.0.45, Ubuntu
Linux 7.1
Reporter: Anil Gangolli
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.
