The IcedTea 2.3.x branch now uses the same version of HotSpot (hs23 from the IcedTea 2.3.x forest) for all builds:

This is following the import of the ARM32 port to the 2.3 forest.

Please test and report any issues as soon as possible. We plan to do a 2.3.11 release based on this by the end of the month. There are no planned security updates for the 2.1.x and 2.2.x branches, so they will become obsolete with the October 2013 security update.
