Orbitz is actively moving to 1.6 and our entire new technology platform is already on 1.5. However with some older apps dating back to 2000 sharing this same monitoring API, it takes time.
Meanwhile, ERMA does have a separate build within the same codebase for 1.5 code including support for Annotations, etc, and we make use of backport-util-concurrent.

P.S. We also have some cool MonitorProcessors that use the java.lang.management package which is new to 1.5.
