The painful saga of our recent JRE releases’ issues with the Oracle E-Business Suite is almost over.  It is expected that a future release of JRE 1.6 will contain a mainline fix for the “Mismanaged Session Cookie” issues that exist with JRE 1.6.0_18 to 1.6.0_21 build 6 (6u21-b06), inclusive.  There is an interim workaround until that new release is available.  JRE 1.6.0_21 build 8 (6u21-b08) is now available and certified for Oracle E-Business Suite 11i and R12. This Build of the native plug-in fixes the ‘Mismanaged Session Cookie’ issue for the JRE 6u21 stream, which could cause a failure of the following functionalities on certain desktop/browser combinations, and particularly prevalent for IE6 and IE7 users: 
 
 - ‘File -> Export’ functionality
- Opening attachments in forms
- Opening an HTML form to a new window from forms.
- Opening an Applet in a new window from forms
- Trying to login again after forms session timeout fails
Special release vehicle for this JRE build This version of the plug-in is only available through 
patch 10021403 and is not available as a download through the usual channels or through the Java automatic update facility. The standard version of the plug-in remains at JRE 1.6.0_21 build 6 (6u21-b06). This fix will not be available through the usual channels until a future release of JRE 1.6. This release also fixes the long standing z-ordering issue (HTML Window opens behind Forms Window) for Windows XP users running Internet Explorer. A permanent fix is not yet available for Firefox users or Windows Vista or Windows 7 users, therefore please continue to use one of the workaround options if required. 
Summary of options for EBS sysadmins At this stage, your options are to: 
 
 - Remain on JRE 1.6.0_17; wait for the upcoming JRE release that includes this fix
- Deploy any standard JRE release later than 1.6.0_17, with the understanding that some of your users may encounter issues related to “Mismanaged session cookies”
- Deploy JRE 1.6.0_20-b05 (released via patch 9915543)
- Deploy JRE 1.6.0_21-b08 (released via patch 10021403)
