My colleagues in the Java division shipped Java Runtime Environment 1.6.0_21 (a.k.a. JRE 6u21, internal version 1.6.0_21-b06) last week.  See the 
1.6.0_21 Update Release Notes for details about what has changed in this release. Unfortunately, this release of JRE 6u21 (1.6.0_21-b06) still has the ‘Mismanaged Session Cookie’ issue that we reported in earlier articles.  This can cause a failure of the following E-Business Suite functions with certain desktop and browser combinations, notably for IE 6 and 7 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
 A JRE plug-in release with fixes for these issues is 
only available through patch 
9915543.  Patch 9915543 contains JRE 1.6.0_20-b05.  This fixed version is not available as a download from Sun or through the Java Update Mechanism (which continues to offer only JRE 1.6.0_20-b02).  This fix will not be available through the normal Sun distribution channels until a future release of JRE 1.6. A fixed version of the JRE 1.6.0_21 (6u21) plug-in is expected to be made available through a special patch download in the near future. 
Summary of options for EBS sysadmins At this stage, your options are to: 
 
 - Remain on JRE 1.6.0_17; wait for JRE 1.6.0_22 or later
- 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)
 I understand that this is a frustrating state of affairs and I apologize for the continued delay in resolving this once and for all.  We’re continuing to work with our colleagues in the Java division to get this set of fixes into the main JRE codelines.  I’ll post updates here as soon as I have more information to share.
