Re: [eclipselink-users] EclipseLink 2.4 @Array Problem.
The generated Descriptor for @Array column is RelationalDescriptor which is a bug by EclipseLink. and I'm using the latest Available JDBC which supports the Postgre Arrays.
Where is suitable to file a bug for it ?

The Error is (The Bold Part) : 

Exception in thread "main" javax.persistence.RollbackException: Exception [EclipseLink-157] (Eclipse Persistence Services - 2.4.0.v20120608-r11652): org.eclipse.persistence.exceptions.DescriptorException

What error do you get?

If your JDBC driver supports the JDBC Array API it should work, check if you
have the latest JDBC driver.

Otherwise you may be able to customize your PostgreSQLPlatform (subclass) to
get it to work.

The Array support has been tested on Oracle, but not Postgres, please log a
bug to have it tested on Postgres.
