We are currently looking at upgrading Ruby to version 1.8.7 patchlevel 72 and upgrading gems to their latest versions.

Before making this upgrade an issue with the User Service will need to be resolved. It was was discovered that a bug gets introduced in the User Service when any Ruby version >= 1.8.6 patchlevel 114 is used. We are currently at Ruby 1.8.6 patchlevel 0.

This issue is caused due to the core REXML parser used by ruby, which in the newer versions of ruby raises an exception when an undefiend namespace is referenced in an XML document that is being parsed.
