Json-lib supports both Groovy and JRuby for quite a while, perhaps you saw in the news that JRuby 1.1 was released a couple of weeks ago, well Groovy 1.5.5 was released today, that prompt me to download both versions and upgrade Json-lib's dependencies along the way. Speaking of Groovy, previously to version 2.2.1 Json-lib would automatically enhance classes to use the
as
keyword to perform type conversions, but as Kohsuke noted, it broke Hudson in unexpected ways (MetaClass magic gone bad) so from that release onward it no longer enhances classes unless you tell it so, which by the way is quite easyThere have been other issues that have been solved as well but I think these are the more relevant to mention for now, as I'm still looking for a way to add generics to the library.
