We have a problem when using AIX JDK 5 beta (IBM) on AIX. The server is running JBoss 4.0.2, Hibernate 3.1, DB2 8.2.2.

On entering data on the client, an empty data row is inserted to the database.

Updating the row subsequently does not update in the database but no error reported.

This problem does not occur in the Window environment using Sun JDK 5 with same configuration (JBoss etc) as AIX.

Any one encounters similiar problem ?

If the only difference between the two environments is the jdk/os , perhaps you will find a solutoin faster in a different forum.

Do you have log files with show_sql set to true ?

In looking into the (java.lang.reflect) AnnotatedElement implementation class, Method.java, the Sun Window JDK version uses AnnotationParser to retrieve annotations and the results are correct.

In contrast, the IBM JDK 5 beta on AIX uses AnnotationHelper class which in turn uses other native classes to retrieve values. The Boolean values always retrieved as false, even it is not specified.

In my scenario, the Hibernation Class, AnnotationBinder.java, uses AnnotatedElement.getDeclaredAnnotations() and failed to get the correct value if it is of type boolean. It always return false. Because column Updatable and Insertable flags are false, the column tags are never inserted properly into the SQL in BasicEntityPerster.java (Hibernation Class), that causes a blank row inserted into the database.

Looks like a bug on JDK 5 beta.
