Jim Locum commented on HHH-2412:
--------------------------------

FWIW, my system exhibited very similar behavior to [Ben's|http://opensource.atlassian.com/projects/hibernate/browse/HHH-2412?focusedCommentId=33605&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_33605] comment above.

The solution for us was upgrading our JDBC driver implementation and Hibernate to the latest versions.

Before:
Hibernate 3.2.6
jt400 6.2

After:
Hibernate 3.3.2
javassist 3.9.0
jt400 6.5.1

> Hibernate code cannot be compiled under JDK 6. Problems and possible solutions:
> 1- org.hibernate.jdbc.ResultSetWrapper implements ResultSet. But in Java 6, there are big changes in Resultset interface, and maybe 20+ more methods needs to be implemented in the ResultSetWrapper class. i would suggest eliminating this wrapper class once and for all, because it is only used in one method (in ColumnNameCache, getIndexForColumnName method) and i dont think there is a justification for using that wrapper class.
> 2-  org.hibernate.lob.SerializableBlob needs to implement new Blob interface methods:
>     public void free() throws SQLException;
>     public InputStream getBinaryStream(long pos, long length) throws SQLException 
> But, if this class is publicly accesible or used by API's back compatibility issues needs to be checked.
> 3- Same as number 2, org.hibernate.lob.BlobImpl class needs to implement new Blob methods.
> 4- org.hibernate.lob.SerializableClob class needs to implent new Clob methods.
> 5- org.hibernate.lob.ClobImpl , same as 4.
> In fact, Java 6 has a lot of JDBC improvements, maybe a java6 special extra package can be created., but that is a whole different issue.
