this is more of an issue of the Oracle JDBC driver. The fix included in 2.4.2 final is more of a defensive coding mechanism to work around this issue. The 2.4.2 final release has not yet been tagged, but you can grab the source code and build it from the following location, where the fix is included: https://svn.jboss.org/repos/portal/branches/JBoss_Portal_Branch_2_4/ btw- what has changed in your environment between when file uploads were working vs when they stopped working.
