The dependencies for JavaMoney are currently

• 1.0.1 (API)
• 1.1 (Moneta RI)

Both were updated in the last few weeks to

• 1.1 (API)
• 1.4.1 (Moneta RI)

Although Moneta 1.3 and above are modular, a BOM with the identical Maven coordinates as the earlier JAR module makes upgrading it rather easy and especially the API is fairly backward-compatible, so it could be in the interest to support the Maintenance Release 1 of JSR 354 because it also resolved the license issues earlier API versions before 1.1 had.

I'm not sure about a backport, I leave that to you, especially the upcoming 7.x releases should consider it, earlier versions may benefit from the license resolution, but it may not be that crucial.
